Hello! I got my iPod touch almost seven months ago in November and I am very pleased with it. However, recently, I've been using it quite a bit as I'm home alone since school is out. I usually use it holding it in both hands but using only my right thumb to touch the screen. If I use it for a while at a time, my whole right arm starts to hurt. if I bend my fingers back, my wrist hurts. I cannot fully extend my arm. my thumb aches if I contort it certain ways. I'm young and healthy, and this is the only reason that I can think of why this is happening. It is not excruciating pain or anything like that, but it's noticeable. Also, I am 14 years old but I am a pianist at a college equivelant level, so I can't risk my hands like this. Any help?
