Hi

I've just started following this thread. Just wondering with the tests that you've had whether or not you had any tests for compartment syndrome?? Apologies if this question has been answered in some of the other posts - I've just skim read. Tests for compartment syndrome are measured by placing a catheter in to the relevent compartment (probably in your case the anterior compartment) and measuring the pressure (recorded in mmHg) this is usually done after a period of exacerbating exercise such as running for 5 mins. If you haven't expolored compartment syndrome as a cause of your symptoms, then you may want to look in to it.

Basically compartment syndrome is when there is increased pressure within a muscle compartment. For whatever reason the fascia surrounding the compartment can become inflamed and irritated leading to thickening and decreased elasticity of the fascia. As a result, when the muscles try to expand during exercise, the surrounding fascia doesn't causing compression on the muscles, reduced blood flow and consequent pain. Your symptoms are therefore due to compression and pressure on muscle tissue and the blood vessels as opposed to nerve tissue.

Again I apologise if I've inadvertently gone over ground already covered but if it isn't something you've looked in to you may wish to!!
