Hi, I've suffered from health anxiety for about 2 years now. I am very concerned about one of my symptoms though. I had a sunburn burning sensation on my lips and nose and up both sides of my nose. This lasted for a few days, and I get burning patches all the time now whenever I'm anxious and think about it. Can this be caused by anxiety? I do remember at the time I was worried about getting a cold sore, as I had read that it can be spread to other parts of the body. I have seen a neurologists and he believes just anxiety, also my brain mri was clear. Also, would something like ms only affect one side of the lips and nose as opposed to both? I have read that the nerves control the feelings in either side of the face, so wondered if it would only affect half the lips and nose. Thanks
