Hi, This is the second time it's happened in as many months. Just after playing the trumpet I have something to eat and a blood blister forms on my soft pallette, which just gets bigger and bigger until it bursts - really bloody, yuk, and painful. This time I've rinsed my mouth out with antiseptic, so should be okay. My questions is - does this happen to anyone else? is it caused by trumpet playing or something completely different, and should I go to the doctors? The doctors is a good option but I'm in Japan and so have problems with the language. So, if it's common amongst trumpet players, I'll leave it as it is. What's your prognosis "doctors"?
