Does anyone else get this? I get very anxious especially around change and things out of my control. I used to get cold sores but for months I seem to be having a week or so of hard tongue and /or mouth ulcers. I've changed my toothpaste and tooth brush for the ulcers etc but the hard tongue I think is a result of stress. It's so uncomfortable and I just can't relax it. Anyone else have anything like that?
