I can totally relate to your leg pain. I am having the same thing, Tylenol and Advil do nothing apparenty because it's a nerve thing. I can tell when I've done too much in a day based on my legs the next day/night. They were really bad yesterday, so I took a Klonopin before bed. That helped a lot, but I didnt like being the zombie today that it makes me. I'm not sure what Flexeril is for, but I am thinking of asking for Baclofen, hopefully to take as needed.
Please do let us know what you find out tomorrow!
