Calluses are interesting. They are the worst when you need them the most, at the beginning when you're likely to be practicing the most.
Only a thing or two to add to what has already been said here: one, is that you might want to check your technique a bit. It's possible that you might be playing too hard. I recall playing much harder in the beginning, when I played w a drummer that played really hard. (He still plays really hard, too...). As I calmed down, the calluses ceased to be a problem. Although years later, they occasionally bark a bit on a ten hour day.
Another fun little "factoid": my wife, when she was in high school, used to have to deal with heavy callus building as a gymnast. Her hands would absolutely be torn to shreds with broken raw skin. She received some really interesting advice: pee on your hands. She tried it and said it worked amazingly well, healing her hands miraculously. (any doctors or scientists out there wanna weigh in with an explanation here?? Ha.) I have no idea if this works, and it might be total BS, but if your hands are really raw, you might consider it!!!
My first post btw. Looking forward to reading and posting here.
