hmm...very interesting. Glad you got an answer at least.
I have compartment syndrome in my legs...basically as it was explained...you have 6 muscle compartments in your leg and 2 of mine are effected. Basically the muscle grows too big for the tendon to stretch...causing pressure in the compartment, pain, tingling, weakness to leg.... until the pressure can be relieved by the dr. cutting "windows" in the tendon to relieve the pressure.
I have tingling in my arms now too...been off and on now for a number of years...gets old. I used to work at a place where I used alot of my arms...that's when I noticed it. I'm tired of dr.'s visits right now. So I feel for you.
Hugs and hope your recovery goes well once you figure out the next step,
