i also am a runner and I have just gotten out of the hospital for DVT in the right calf and right thigh.I also felt some discomfort after runningand also before, while i was exercising the pain would go away. The next problem that occured was severe swelling where my calf was about 2 times it's normal size. So go in and have it checked, I just thought that i had strained the muscle and it was not a big deal, But it turns out that was not the case.
