About two weeks ago i was messing around with my higher range, trying to pass my double a. I could hit a double c, but not the b flat or b natural. so i kept playing up there trying to experiment different things, like tongue arch, and lip rolling ect. But after that day i havent been nearly as good as i was prior to that day. i looked on the underside of my lip (the part that touches my front teeth) and noticed that there is a piece of tissue missing from my top lip. I can play just as high as i usually can, but im missing allllllll of my power, i cant play anything loud. so i took 3 days off just buzzing pedal tones on my mouthpiece, and when i came back, i was a little bit better but still missing alot. So is there any kind of cream of ointment i can apply to that spot of missing tissue underneath my top lip?
