If you can get a copy of the written MRI report, you can post that info on the spinal forum linked in a previous post.
It helps to see the wording used on the reports.

Soft tissue injuries can be as debilitating as nerve /bone injuries, so perhaps an expert/highly skilled chiro, advanced PT, or even therapeutic massage or just an assessment/evaluation by those, might be something to look into..if you haven't had any "hands on" therapy.

Have you tried a muscle relaxant like Flexeril?

With my profound PN I suffer terrible thigh cramps, so I always take Potassium at night, hoping to help.

I don't know of other forums, so I can't help you.

It sounds as if you have gotten the maximum professional help, Chris.

The contraction is so awful, isn't it, because it feels as if the muscle will pull completely away from your bones?

Are the crutches the result of a constant contraction and pain, or from damage done, or to prevent the contractions?

I was wondering the same thing, the crutches are needed due to the fall, sounds like it was a nasty nasty fall. Magnesium is critical for spasms issues. Many are deficient in mag anyway. Soft tissue issues are to be considered. With my knee issue, it seems like I have more soft tissue issues.
