How does a Bulging Disc Occur?

health wellness

A number of things can cause a bulging disc to occur. Understanding the cause can sometimes be an important part of the treatment plan, because the patient should take steps to reduce the risk of recurrence or additional strain. Knowing the potential causes of bulging and herniated discs can also help people avoid activities which could threaten their spinal health.

The terms “bulging disc” and “herniated disc” are often used interchangeably. In both cases, the condition is characterized by a problem with the spongy discs which act as shock absorbers between the vertebrae. Normally, the discs are aligned with the spine, but sometimes the jellylike fluid in the discs presses against the outer walls from the inside, causing a disc to bulge out from between two vertebrae. This condition is sometimes accompanied with significant pain, because the bulging disc can start to press on the nerves of the spine. In the case of herniated discs, the outer casing of the disc actually splits, causing the fluid inside to leak.

Age is one of the leading causes for bulging discs. As people age, their tissues lose elasticity, and this loss can cause the tough outer envelope of the disc to weaken, allowing the fluid inside to bulge. Bulging discs associated with age may also be accompanied by degenerative conditions like osteoporosis, which weaken the spine, making it more susceptible to developing bulging discs.

The risk of developing a bulging disc can be increased by smoking, according to some studies, and taller individuals also seem to be more prone to bulging discs. Weight is also a factor, with people of heavier weight naturally putting more pressure on their discs. People with strenuous jobs are also more likely to develop bulging discs, especially if they do a lot of heavy lifting or bending.

Strain can cause a torn annulus, tearing the outer layer of the disc and causing it to bulge. Spinal trauma and degenerative diseases can also lead to a bulging disc. However, many people develop bulging discs and are entirely unaware of it in the early stages, until the bulge protrudes enough to start putting pressure on the nerves. Pain from a bulging disc may also be dismissed as pain from general spinal strain, which is one reason why it is a good idea to seek medical attention for persistent back pain.

my daughter has the same problem. she has just been told she has a bulging disc. she is only 14 and is in a lot of pain, but the neurosurgeon won't operate because of her age. he said the risk is too high, and having the operation could actually make things worse.

Hello my name is Skylar and i have curvature of my lower spine, along with bulging discs in my lower spine. This causes me a great deal of pain not only in my lower spine but also in my legs as well.

I started having this trouble about a year and a half ago. I was constantly missing school because there were times where in the morning i couldn't even get out of bed. I told my doctors all the time about my troubles but all they would do was just give me some pills and tell me to take them and that's all. It wasn't until just about two months ago that they finally started looking into it but by that time it was too late because as soon as i turned 18 my insurance dropped me. so now i do not have any insurance nor can i afford it.

I was told that i would have to have surgery but the day i found out what was causing all my pain and how severe it was and that i would have to have surgery to fix it my insurance was dropped and now i have to live with this. I am 19, very athletic, 6 feet tall and weigh 168 pounds and i need some one who can tell me what i can do.

Sounds exactly like my early symptoms. Especially your statement that you had "a very tired feeling like I cannot walk another step." Early on with my trouble I often used that exact same description - I found if I forced myself to keep walking I would get that same "tired feeling in my back and legs" as if they would lock up and quit on me from exhaustion if I tried to force one more step. And I had my condition for almost 10 years - saw an orthopedic specialist, a neurologist, a rheumatologist, and my family doctor every 3 months, and suffered two incidents of temporary paralysis for about 20 minutes each time of my left leg and foot. When I finally woke up one morning and had such agony in my left thigh, left groin area and left hip into my lower left back so severe that I was literally screaming for someone to call an ambulance, I demanded an xray or ct scan or mri to prove to me that there was nothing there - my family doctor finally ordered a simple half hour mri that finally showed two huge, bulging disks compressing all the nerves in the entire area, and I had my diagnosis finally and was told permanent paralysis or death were "imminent" because lack of diagnosis and treatment put me at the point of dire emergency with my condition. So much for the level of health care provider expertise in this country. It is benign neglect. If an obvious problem doesn't jump out at them and hit them in the face, doctors in U.S. pass you over and pass you on and ignore you when they should be more concerned and ramping up pursuit of diagnosis. Instead they wait until the patient comes back ten years later, paralyzed and near death - and then they can tell you what you have. No kidding - but I could do that without a medical degree by that point too! I think you have bulging disk in its early stage and it won't show up except on the most sophisticated tests and by a doctor intent on finding it. Tell him the survival of his medical practice is dependent on him finding and making an early and correct diagnosis and watch what will happen - you'll be cured in half the time. But doctors are the only people allowed to get away with nonperformance in this country and still get to keep their jobs. They don't get fired. Try working in a factory with that rate of performance on the job. You won't still have your job 10 years later. But your doctor will have his - and double the patients to boot!

I cannot find a Doctor who can help me. For the past year I have been having trouble walking. My thigh muscles feel like they are very weak and sometimes it is an effort to walk distances. I don't have pain just a very tired feeling like I cannot walk another step. My balance is not the greatest either. I have had an MRI of the brain and an MRI of the spine, nerve test and I lost count of how many blood test's.

I have been to two neurologists who obviously were not sharpest students in their class, as they cannot diagnose me. I have a stack of bills that are growing from this group of sorry Doctors. One thing that I did find out is that I have a moderator bulging disc. I am hoping this could be my problem all along. I would welcome any feedback.

Otherwise I am healthy, I am 58 years old have always been healthy and active. I am 5'8 and weigh 155lbs. I take no medication and stopped smoking 6 months ago. All I need is one on the ball Doctor to diagnose me. Anybody know one?
