question: Hi, I have sores in my mouth and around my elbows. I have had this before over the last 3 years about 4 tines. The sores on the elbows are distinctive. They have a dot in the center surronded by a ring. The are itcy at first . The ones in my mouth are all over the inside, making it hard to eat and very sore. It's as though the whole layer of skin inside is coming off. It lasts for about 2weeks. Please help. My old gp said maybe an alergy or someting. Alergy test were never done. I really need to know what is wrong as this is really painful when it happens and also would like to know ic I can prevent it. Thanks
