Skimming about a week and a half ago, I started getting a wicked charlie horse in my left thigh. I figured it'd work itself out so I kept going but it just got worse, and then started up in the other thigh, too. It's way up in the front of the leg, right about groin level, but further forward. 9 days later its a lot better but still a little sore. I can run fine, but if I try to sprint it starts up again, which is killing my skimboarding.
Anyone have a similar experience or have an idea of what exactly it is (I'm guessing a pulled muscle, but I don't know which one)? Any ideas for healing it faster or preventing it in the future? I've been doing quad stretches, but I think it's higher than that. Lifting my leg up and pulling it in towards my body helps a bit.
