@MissMuffet - I can totally understand your reluctance to have surgery, but sadly this is the only option left when regular treatments have failed. (I am guessing you have tried other things already.)
It is so much better to catch things before they progress too far. I have tendinitis in my foot, which is currently being treated with special shoe inserts. I already had a cast and medications, so fingers crossed this is enough.
If I do have to have surgery I'll accept it, but in the meantime I'm doing everything possible to recover without it. It's pretty difficult to rest enough when you are an active person.
