Shoot yeah, it happens to most sax players, especially if they are in marching band. Unless it is hurting you I doubt you should worry. Word to the wise...unless the doctor plays sax as well, he won't know what to do with it. I wouldn't let them cut on it any. If it helps, there are some gards you can put on the thumbrest that make them softer. Hope this helps.

So your saying after years of playing the saxophone your actuall thumb changed to deal with the stress of holding your sax up? It actually go stronger then the other one? And your saying if I say played saxophone for 18 years, wait a tic I have!!, my hand would have altered because of it? [dramatic pause while I look at my hands...] YES You are correct my hands do look like they have been altered by playing saxophone for an great many hours while my body developed threw atolesance. How did this happen! My teacher never warned me of this!!! The short story is, Yes they do, if you do anything for a prolong amount of time esp. during atolesance your body will adjust to it. My fingers at rest fit normally to the keys of a saxophone from years of playing. My pinkies are probaby strong then your legs.
