Heya :3 I've never posted to this community before, but I have an emergency! I'm a French Horn player and I have a cold sore (or blister or some kind of spot... I'm actually not sure) on my lip exactly where my mouthpiece goes when I'm playing the horn, and it's making it painful and difficult to play. I can reposition the mouthpiece slightly to make it less painful but then it makes some notes harder to play, and doesn't do wonders for my tone either. I'm all right with middle-range notes (middle C to A or B) but the higher the note, the more painful it is, and I also have difficulties with changing quickly between a high and a low note.
So, my question: has anyone here ever played the horn with a cold sore and/or can give me any advice on how to deal with it? Abstaining from playing the horn isn't an option since I've got school music practices to go to, a recording in one of them tomorrow and a BIG concert on Saturday, the last of my school career, where I'm playing first horn in two pieces... which is why it's an emergency. I've had it for a week and it doesn't seem to be going away normally, though I can still hope. I've just started putting Bonjela on it which is a gel that treats mouth ulcers, cold sores and the like... but in the event of it still being there on Saturday I want to try and play normally, even if it hurts.
