This is probably an immune system condition. You need to find out what you are eating that is activating your immune system and eliminate that food from your diet. You know the problem foods because it will upset your digestion in some way after eating.
I'm quite healthy otherwise, I have been told its an inherited skin problem, I saw the YouTube clip with embarrassing bodies with the oldish lady and I have about a hundred of these and will be upset if I finish up like the lady in the clip.
If I were you I would consult with a naturopathic doctor. Many things that they say on the internet and in established medical circles are just pure nonsense.
