Anyway, I've been having an issue with my leg. I always stretch before and after my runs, but everytime I run my left leg hurts for the rest of the day. Not just a little ache either, like hurting so that ordinary pain relievers aren't helping. I put icy hot on it, I take a few ibprofen, but unless I take something really strong (as in a percocet) it hurts. It's an area behind my knee, not in my knee, but on the back of my leg right above my kneecap to a little bit below. I thought maybe it was hamstring, but it seems a bit low. Any ideas on what it could be? Or what could help it? It never hurts the day after I run and it's always the same leg that hurts, my right leg never hurts after a run.
Also, I want some super cute pants to run in and our craptastic PX never has what I want.
I want something like this:
