About a year ago, I had a very intense day of playing, I think there was about 6 or 7 hours worth, and I felt okay by the end of the day, but for the next few weeks my endurance and range had greatly declined. My senior recital was coming up so I took a couple of weeks off of playing, as per request of my teacher, and I went to the doctor. It turns out that I have a small cyst right on the edge of where I play on my bottom lip, causing some "leakage." The doctor suggested surgery, but as I started to read up on that, I don't know if I want to risk it or not. Does anyone know of any other treatments or a good doctor in minnesota who might know better? Or would just cutting it out be okay? I was able to do my recital, but I play lead trumpet in jazz, which got increasing tougher.
