Hey, I`ve just been reading
http://www.lunnflutes.com/ho1.htm#alex this article on the Alexander technique for flautists. I already use this to eliminate any pain or discomfort felt when playing the flute(ie. pain in the hands/back/forearms/neck etc). It`s designed to control breathing and posture.
It`s a useful thing to learn if anyone`s interested. If not... well... this post is then just a figment of your imagination and you really should go and see someone before it starts getting serious.
