Hello everyone, I am getting sores inside my lower lip area. Currently I have two, and I have had several others each at separate times and once they heal more come back. I am in music camp, and I'm playing more than usual but nothing too crazy. I don't have a mouthpiece pressure issue, so it's not related to that... Any ideas on what is causing this? And a solution to this? I often get sores from acidic foods but I haven't eaten anything acidic in excess lately. Thanks!
