Unfortunately the benefits of swimming were short lived. My legs started feeling tight earlier this evening. In the last two hours, they've gotten progressively tighter like a rubber band being pulled (around the IT band area). And my walking is almost back to where it was yesterday. I guess when the usually happens I'm asleep and wake up this way. Its really uncomfortable when your muscles just start tightening on their own.

Took some baclofen and hopefully it helps. Can't go to the pool until tomorrow morning. Is there a point to going to the ER for something like this, or do you just try and manage as best you can?
