You will be surprised about how much of the above symptoms will go away once your intestinal tract is cleaned out and mucous membranes are working as they should.
You might have some parasites and candida that area leading to leaky gut. The gut is the most important area to good health. You mentioned you have some reactions to certain types of foods. Your tight junctions in your intestines might be compromised and that is what is leading your to develop immune reactions and rashes. The immune system is actually located in the gut...just as is the nervous system. Hence why I'm saying the gut is the most important part of healing.
So I would concentrate mainly on treating the gut.
Also look into heavy metal chelation.
And work on your stress load.
And DON'T LISTEN TO DOCTORS! They will only make you worse.....they area trained to fill you up with a new prescription medication with each visit...stuff that makes the already compromised gut even weaker.
