It is apparent we are both in the same club - the Club of D'Nial In the fall of 2011 I had a nasty fall on the mountain bike trail - the only thing fast about that ride was the fall and I snapped my neck - helmet hit my back. After 2 days my neck suddenly expanded to resemble a piss*ed off Gila Monster. Did I go to the doctor? Of course not! It took me a full month - and my neck was still swollen - had a BAD case of whiplash that I am still recovering from...we are indeed related

I don't understand why your doctor was resistant to getting both MRI tests. I know my own doctor is strongly resistant to getting multiple images because of the exposure to the body from whatever technology is used, but that is my doctor. I've had a lot of issues in the same area you have that was related to a strained sartorius. Some of it may have been connected to some minor hip arthritis, but just because it is there doesn't mean that it added to my symptoms.

Hang in there and let us know how things go!
