Dermographia, also known as dermatographia, is a skin condition that causes itchy, red lines to appear when a person affected with the disorder scratches his or her skin. The lines that appear from dermographia are not serious, but they can be itchy and uncomfortable. In addition, these lines can last for several minutes after scratching is complete.
In a person with dermographia, specific skin cells called mast cells have a tendency to be overly sensitive when they experience minor trauma, such as that experienced when a person scratches his or her skin. When a person with dermographia scratches his or her skin, it causes the mast cells to release special chemicals called histamines. When histamines are released in a person with dermographia, the small blood vessels dilate. As the blood vessels dilate, or widen, it causes the characteristic redness and itching associated with dermographia.
Experts are unsure of the cause of dermographia, though most believe it is associated with allergies. Despite this belief, several patients afflicted with dermographia have no other symptoms of allergy. A person with dermographia can avoid symptoms by refraining from scratching his or skin or irritating it in any way. It is also best to avoid wearing wool clothing, which can scratch against the skin and cause the lines to appear. Harsh soaps also appear to irritate the condition.
In some cases, antihistamines are prescribed to help treat dermographia. Other times, the dermographia goes away on its own. For some people, the condition never really goes away.
Determining whether or not dermographia is associated with allergies can be difficult if the allergies are not already identified. This is because a common method for testing for allergies involves rubbing various allergens against the skin. Since the skin of a person with dermographia is irritated by rubbing, every allergen will appear to cause a reaction.
For individuals with dermographia, it is necessary to perform blood testing rather than skin tests to determine possible allergens. If the test indicates a specific allergy, the person with dermographia may receive allergy injections to help battle it. This does not, however, guarantee that the deromgraphia will subside, because the allergy is not necessarily the cause of the condition.
Have you tried homeopathic medicines for this? I did for my condition, and although it did not totally go away, the itching did reduce by almost 90 percent and I hardly get it but once or twice a year now.

I'm glad I'm not the only one with this. I've been to the docs and he couldn't tell me what it was. At night it looks like I've been attacked by a bear all over my back because i scratch it, and I've been asked if someone has tried to strangle me because of the red marks around my neck!
It has only been since may this year that this has been happening! I'm booked in for a tattoo in a week and am worried that it will happen then. I had some tats a few years back but didn't have this then! has anyone had a tattoo with this condition before? Please help.

When I turned 19 this had happened to me. I went to the doctor finally, after scratching my self until i would bleed at night. He first said it was scabies. I kind of agreed cause i was living in my college dorm at the time. After using everything i still itched and whelped up. Finally he said my body does not do good with any type of nylon. I played football and the pants were nylon. I am now 23 and this still happens. Guess i am just used to it by now. The last year it has actually started to go away. I have taken nothing for it so far.

I am 25 years old and have had it for about four or five years now, maybe since I was 20. My dad has it too but only got it about five years ago? Coincidence? I think not. It doesn't make sense, must be something we were exposed to, but my mom and brother did not get it, so it's in our genes i guess. I can write name on arm with medium scratching. It varies with different times of the year in severity,
Sometimes I'll put my backpack on and the light abrasion from the strap will raise up a portion of my arm and leave red marks -- not a problem except when i scratch my face and people think i have some weird thing going on. like, what happened to your face?

Wow this is a great find. I got this when I was 30 years old. I am now 42. It came on very suddenly within two weeks when I was working for a gravel company crushing rock (this might be a relationship from a couple of the above posts!). I itched and itched and after about two years of this, I couldn't take any more! I went to the dermatologist and he said that I had this and he prescribed Hydroxyzine hcl. It works well but it makes me very tired and if I don't take it for a couple of days, the disease comes back in a vengeance! I still feel that dull itching sensation every day though and it is embarrassing when I get my haircut or even bump into anything in public.
Why doesn't anyone study this?

thank god i found this! i was getting worried that i was a freak as i had never come across someone with this condition too. my friends scratch their names everywhere on my skin when we're on the bus, lol. i heard of a lady who has dermographia and etches art onto her skin, and gets thousands for each photograph sold. insane.

I am so thankful that I found this! I have been trying to diagnose myself since the docs haven't been any help. Even ended up in the emergency room with what I thought was severe hives a few weeks ago. Been going on for three weeks now. Can't imagine having it forever. Same thing happened about five years ago when I was under a lot of stress. It is worse where my clothes touch or if I even touch my face or scratch any part of my body it gets super hot, itchy and raised. After I wash my hair and body, I feel like I am one big hive! If I take benadryl and lie still and don't touch anything, it subsides. I hate this! I don't want to be doped up on benadryl all the time!

all my life i've had dermographia. i had no idea it was a skin disorder. i thought that welting from light scratches was normal. i always would get raised scratch marks where i touched my skin and only a year ago did i decide to see if there was a name for this and sure enough i have dermographia! it's kind of annoying that there's no real treatment or research on this. does anyone know if it can get worse with time?

Okay so I have Dermographia and it says that it's allergy related. Does this neccessarily mean that I am eating or having contact with something I'm allegric to?

Tingling in your back, which I also get, is more likely to be related to a sedentary (desk-based) lifestyle, and weakness of the back muscles and/or over-extension of the arms and scapula muscle complexes (from typing), which then gets aggravated when you drive (as it's the same position). Recommended to see a physio for a gym routine of muscle-building, and also yoga/pilates for stretching and core-strengthening. - G Fox.

I took acutane for a course of 4 months, and at the middle of the third month i started to have severe allergic reactions. i didnt know it was from accutane and i continued the whole course: 120 units of 10 mg. i took 1 daily. after two weeks from stopping this treatment, i couldn't bear the allergy and i went to the doctor to find out that it's dermographia and urticaria is a side effect of accutane so dermographia is a chronic kind of urticaria. i'm afraid this will continue. really it's very annoying specially when you go for shopping and change clothes, very bad, even when i'm in a resturant when my arms touch the table, raised red lines appear everywhere on my arms :(

i have not been diagnosed with this. they tell me i have uricartia, or chronic hives. it has been two years now, this sounds like me to a T though. if i bump myself or rub on something i welt up and it itches horribly. and it is so hard to stop the itching, i have been on all sorts of antihistimines, xyzal seemed to work, but insurance wont cover it, now i am taking cetrizine, hope it works. it is relieving to know i am not the only one. i thought i was weird! lol

I have had dermographia for three years now. I have also developed a tingling sensation in my back (kind of in behind my shoulder blade towards the centre of my back). Don't know if it is related - but it is a strange sensation that often happens when I am driving long distances. I take Telfast 180g every day (sometimes twice a day). Would love to find a reason for the symtoms......

I am so relieved to find out I am not the only one with this skin disorder. I don't know how many times I've had to explain to people that "oh its nothing" ...or "my skin is just really sensitive". I always try to ignore the itch bc as you know once you start it is virtually impossible to stop. Sometimes I go at it and it looks like i'm a burn victim (hours later).
I am 24 and i have had this since I was 16. It seems to be getting worse so i recently did some research and I saw that dermographia is linked to Myelin Sheath and MS. I may be freaking out but does anyone else worry that dermographia may be an early sign of MS?
Now I am really worried but still a bit reluctant to run off and get an MRI.
Thoughts?

I was diagnosed with dermographia a couple of years ago after my husband built a rock fireplace in our house and we had dust everywhere. Only thing that helps is Zyrtek, but I hate taking it because it makes me sleepy. I don't have a day without the welts and itching.

Oh also as a result of dermographia if I carry any heavy object or slap my hand down on something my whole hand swells up and hurts extremely bad.

Im 15 and for the past two years I had these strange red marks all over me and it itched like crazy, the first year i had it i got blood tested 4 times and doctors couldn't find any allergies and it turned out i had dermographia so i got diagnosed by my doctor with it. I took allergy medicine, for 5 months i didn't have it at all but all of a sudden i got it again and i still have it today.
Its so annoying every time i try on clothes at store i get red lines and itchy all over me and during school if i rub up against someone on accident in the hallways i get dermographia.

I was first diagnosed at age 21 and am now 39. I had about 10 years in between where the dermographia subsided. I have also developed an allergy to cold weather where I welt up and itch terribly. I believe my skin conditions have a heredity component and are triggered by stress.

I hate trying on clothes. I end up having these red marks all over my body.
The way I discovered the name for what condition I have was odd. I was actually getting a breast exam by a nurse practitioner. She said "Oh my you are swelling up!" I looked at my chest and everywhere she touched is where I had the reaction. She said, "I have never actually seen a case of dermographia!" She pulled a medical book off the shelf and showed me. I have had this for years and never knew what it was.

Gracious! I am so glad to finally have a name to this. Always thought I was allergic to myself. I always look like someone beat me up just by touching my face. I thought it was the oils in my hands.

It's amazing to finally have a name for this! I had this when I was a teenager. It used to drive me crazy. It disappeared as magically as it appeared.
I am convinced it was a result of where I worked. I worked during my teens in both a chocolate factory (yes we made hot chocolate powder, orange juices, powdered chicken stock, etc.) I worked there in summer and evenings during the school year I worked at a bakery, and we made bread, literally put it in the oven, took it out and usually buttered garlic bread.
During that time my skin would welt like crazy if anything touched it. In the bakery my friends would smack me in the back (we'd wear halters it was so hot in back) and there I would be minutes later with this huge hand print welt on my back. I could write my name with a fingernail on my skin, and even sitting in the grass, the grass blades would scratch my skin it was that sensitive.
During this time I also would get these RINGS on my skin. They'd start with what looked like a large pimple but it had dry flaky skin in the middle...it would spread until it was the size of a dime or quarter, and in the middle was dry skin...and then it would just fade off into normal skin.
No one could tell me what that was. I thought ringworm cause it looked like it should be called ringworm but was told no...and no one ever could explain what I had then.
So it's nice to see a name for this all. I have to say when I stopped working in both these places the condition disappeared and here I am 30 year years later and it never once re-appeared.
So I am convinced it's something in all those chemicals or perhaps the flour flying around or the heat and combination of all those irritants...who knows.
Don't wear wool...that was excruciating, and I can see why the gal in the mall can't even touch clothing with all those starches, dust and other chemicals which must exist on all that stuff. Just think the hands and machines and crates etc. it's passed through to get to the rack? Wash before wearing everything.

I'm not sure if I have a mild form of dermographia, or if what I experience is just something anyone with pale skin has. I can take my fingernail, run it down the pale underside of my forearm, and, especially if I then lightly rub my arm a bit with my hand (to increase blood flow, maybe?), a bright red line will appear. And I can scratch the back of my neck and create bright red marks, too. Sitting on my hands can really make them look odd, and a tight waistband can create a red mark, too. Also, hot showers leave a large red mark down the middle of my back where the water runs down. No welts or hospital visits, though. So, is this all fairly normal, or dermographia?

the worse thing is trying on clothes at the mall, i look as if i have been attacked by a cougar because the tags scratch my neck and face. my doctor did like it when i went to go show him my condition and i had drawn a palm tree and the words, help my skin on my arm. he laughed and said i would be a lot of fun at parties and then brought in all the other doctors in the office to show them my skin. he didnt give me a cure yet : (
maybe one day i can go to the mall without fear of looking like i attempted to hurt myself every time i go in to try on a shirt.

for years i was misdiagnosed, heat rash, allergic reaction then when i was 24 it was so bad i ended up in hospital with what looked like whip marks all along my back, the itch was making me mad. they told me what it was and my body was so over loaded with histamine that they gave me drugs normally given for leprosy just to calm it down.i now take antihistamines every day but this is to stop the itching which i feel every second of the day. i get a really bad attack every 7 or so years, my specialist said thats because my blood has totally renewed itself and we have to start all over again with the super drugs. on the funny side i used to write telephone numbers on my arm if i didnt have a pen near as it would stay for about 15 mins! id love a cure, id love one day without feeling itchy

Well, I guess that I have this as well... If i scratch or rub my skin I will welt up and the area becomes itchy and hot feeling. I had one doc that pretty much told me that I was allergic to myself.... All this time I though I was the only one...

I also have this, although i notice that there are times when i don't experience it. Not sure but its kinda seasonal for me. I am allergic to zinc, I don't know if it has something to do with it. I hope they do more studies about this coz even though its not that serious, its still irritating. And very disturbing at times.

I had dermographia on and off all through my childhood but it was very random and did not happen very often so it was not officially diagnosed until I was 14 when I had an outbreak so severe I ended up in hospital doped up on antihisthamine drugs with welts covering my entire body (even the soles of my feet and my eyelids were welted). I saw a specialist who diagnosed it as dermographia and he told me I should grow out of it in time..... I am now 27 and still get horrible welts everywhere every time I touch my skin on a daily basis. If anyone ever discovers a cure please please post it here!!!

I am not sure when I first developed dermographia, but it comes and goes - I am now 37. I think there may be a hereditary component because my five year old has had it on and off since he was two.

i also do have dermographia. Never knew the name and not medically proven by doctors but I am sure i am having it. I had it a few years back, when I was 15/16 too. Yup, people amused when seeing I can write my name on my arm.
I also experience sudden rashes on my skin, which I do not know why. Sometimes, I do not get the rashes when I am eating seafood and sometimes the red spot just appear at anytime without I realizing it..

I'm 23 and have had itchy skin for several years, possibly due to a natural feather duvet. Yet only since last Winter did my scratching produce symptoms of severe dermographia. Very strange!
Believe it or not, the only thing that instantly soothes my skin is a brand of "fashion" body lotion (Ted Baker). I don't want to be taking pills or stockpiling that lotion for the rest of my life though...

I have had Dermagraphia since the age of 5 or 6. At school when I was younger children would be amused that they could write their name on my arm, but now that I am 34, not so funny, especially when you go out socially and then you scratch yourself and it hives up.

Is it possible, dermographia may also involve the myelin sheath (around the nerves)? Also, if true, could sulfer help the condition?
