thanks for the tips guys. I know I have perfect technique, even my guitar teacher says so. I just think i've been pushing myself too hard. Sometimes don't even care, if my wrist hurts i keep playing anyway. My teacher told me just to stop if i get pains. I think it's different for everyone, some people play all their lives and never have problems, some play 2 years and their career ends already. But I'll still be watchful and take in mind what you guys have said.
