After I practice for a few hours on the piano, I feel a strain in my hands (I don't know if strain is the right word, It doesn't hurt or anything. It actually feels good because I feel like I have exercised my hands properly). In any case, I usually stop practice at that point, because I don't want to injure myself (RSI style). My questions are:
From where does the strain usually originate: muscles, tendons etc.
Is there a way to relieve it or deal with it beside resting. I mean something in the line of soaking my hands in hot water :).
