Leg pain is my main symptom right now...I can't stand for more than 5 minutes before they really start to ache, esp the shins. If I move around a bit they feel better for awhile, but then they begin to weaken and hurt.

I take zanaflex, a muscle relaxant. It's not working as long as it was before.
I take a prescription NSAID for arthritis pain but it doesn't touch this pain.
