Stop PEing completely until it clears and when you start again be sure to warm up and try not to overdo the exercises. If it isnt better in two days you probably wanna see a doctor. My guess is that you just worked it a little to hard, and that itll clear in a couple of days. On the other hand you dont wanna take any chances, perhaps youre more suceptible to damage than others, in that case you definantly wanna take more care when doing your exercises.
