My son has been complaining of burning and stinging lips for about a year. They have become so bad that he cries sometimes. They are not chapped. They do swell sometimes. I am going to take him to a dermatologist but Im afraid it will just be another issue that is unsolvable as every time we go, they acknowledge neurological/ vascular problems- but have no answers. He is a really tough kid, but this is getting worse and I'm sure it is related to whatever caused my nerve damage.
I found some info on fungal infections which are interesting. Cant think of what else it could be.
