Being a pianist is a tough for me. I have hyperhydrosis which means excessive sweating. I sweat excessively on my palms, feet, arm pit, face, legs,.. I'm not overweight but I know my parents did have excessive sweat when they were young. ANyhow, I just don't feel comfortable when playing on public because I get sweat. I have to wear dark silky clothes to hide the sweat stains. They're not little sweat, I mean HUGE sweat. Both of my underarm and palms are my problems. When practicing either the room temperature are warm/cold, I just can't stop the sweat dripping in my armpit area. It stresses me out too because I usually wear bright shirts then if someone ask me to play I always refused. One time I was wearing a colored shirt then after wards I looked down and saw the sweat stain on my shirt. It was horrible and embarrassing.
I really don't know how to cure this. It affects my playing and I might want to stop playing the piano. ;(
