I hope this has been posted to the right forum or thread..... I've just recently started to recover from yet another fight with the dreaded, and seemingly unavoidable, intermittent lip "discomfort". In other words, the pimple on your lip that is too close to or right inside the embouchoure ring that makes playing painful on the chops! I've not been able to play for two days, and feel certain that when I get back to it, probably later today or tomorrow, that I'll have lost strength, endurance, etc., and will have to work doubletime to catch up again. Yikes! It seems that, no matter what precautions I take in trying to keep the mouthpiece free of bacteria (rinsing and washing, including using the mini-cleaner, and occasional spraying with mighty mist, or an quivalent alcohol based mouthpiece spray disinfectant), that I get some pimple every three to four weeks. IS THERE ANY WAY THIS BE AVOIDED? What do you professionals do when you have a lip impediment on a day of performance!? I once read that prolonged playing on chops with a difficulty like a pimple can lead to permanent damage to the inner linings of the lips and gums where oils are produced in between the tiny layers muscle tissue. Is this true?
