So since its Winter Break I decided to take a break from playing trumpet for like 3 or 4 days. Because my previous section leader saifd that I should rest my chops 2x more than I practice and before school let out my school band has been doing alot of stuff the week before school let out we had alot of 9 o clock practices and alot of performances. So I've noticed that I've had this long blister going acreoss my top lip for a while and I thought nothing of it because they usually go away after a while. But this blister has been here for like 3 weeks and I think that its starting to affect my playing. Can you guys suggest me something that would help it heal faster?
