Lately I have been experiencing burning...

[T.Horton]

not while I urinate but while I jump rope - I don't know if it's tendinitis (I do have a history of it from my baseball days). The pain is in both shoulders and it's bearable just kind of annoying. Anybody else? Or am I just confusing this with just normal lactic acid build-up....

Same thing happened to me. Still burns after a couple days. I hope it goes away on its own.
