Ok so lately my center of my top lip is killing me, the very center no where else. I use the muscles around my chin are to play with, therefore it is no embouchural I dont think. Anyways nowhere else on my mouth hurts, except that very center of my top lip, I play once in band class which is 45-1hr uisually I go home and do 30-1hr on techquincal studies (double, triple, slurs, etc) and I wait a while and I then I go back in to practice around 7-9 that night and do endurance/range exercises, and lately my lip at the center is swollen towards my teeth, not on the visible outside. This is very annoying becasue it feels like a fat lip when I play and sometimes itll turn inside out whenever I pull all the rest of my embouchure tight. Ive lost 2 notes in range, about 5 min of endurance, and tone quality. It sucks and were havein our tryouts for symphonic right now. I started about a week ago with me trying to play abblasen, But I didnt think that was the cause. I also have solo to play at a competition this week on saturday, qucik help/ suggestion?
