My brother has had prblems with his mouth for about 6 years now. The symptoms are multiple wall to wall ulcerations extending to the lips, but not outside the mouth. These can last for up to nine months at a time. These sores have been tested as not viral originated but could possibly be allergic reactions to certain foods; some of which he knows about. These findings come from a doctor of reflexology or possibly kinesiology. The sores are having a huge effect on both his physical and mental health. Does anyone have any ideas about anything which may ease the pain or even take them away completely?
