Does anyone have any experience with playing with a massive pimple on their lip (mother is convinced it's a cold sore, but it looks, feels and acts like a pimple)? Or better yet, does anyone know why they occur and how to avoid/get rid of them? I've gotten them before and normally I just lay off for a couple of days, but I have way too much this coming week (9 performances and a couple rehearsals for my junior recital next week).
Any help? :/
