The doc told me so but I never felt no pain while I was doing that and I was doing it for like 2 yrs, but I don´t feel no pain now either since I stoped. So I don´t really know what to think except that it depends on human body. Doc said that it depends how easily you get sick and get infections and also it´s dangerous to play while you allready have a infection and are sick.

That´s encourages me pretty much ´cause I´m almost never sick.

One more thing. Don´t overplay. Let´s say that you´re doin´ 4 hrs evryday than don´t suddenly change into 10 hrs, than go back to 4, than 2 than 8... I think playn´ regularly is important. 1 our 2 days probably don´t mean nothing but if you change it constantly, than I think you run a bigger risk for tendonitis crap.
