Good news ( for me ). The lip balm is working. The sore has shrunk in size and the soreness pretty much gone. Still a small scab that I do not want to disturb. But yesterday afternoon I managed to play two easy tunes using next to zero pressure. And this morning I did ( almost ) a 20 minute routine I have been doing daily for the past 2 and a half years. The routine ends with 5 expanding scales. The first G on the staff to top space E, the second first space F to to line F, and the third goes from bottom line Eb to first space G above the staff. I was able to play those three with next to zero pressure, so that is where I stopped...for today, anyway. Even though my tone stinks, it is okay because right now I am only interested in working those face muscles around the lips. I feel good !
