I've been on antibiotics for years.

Thyroids testing normal, although a lot of my symptoms feel like they could be thyroid related.

Do you think the skin issues could be candidiasis Or does Lyme cause skin issues too.

Infections: Bacteria, viruses and fungi are common causes of skin rashes.
Infestations: Some skin rashes are caused by tiny parasites such as lice and mites.
Irritants: Abrasion (clothes, diapers, etc.), heat or sun exposure, cosmetics, an overly dry environment.
Allergies and Reactions: Insect bites or stings, plants like poison ivy, certain foods, chemical pollutants, medications, chemicals found in household cleaners - and many others.
Systemic Illnesses: Skin rashes may be one of the symptoms of a primary disease like rheumatic fever, Lupus or (((((Lyme disease.)))))

After I added cod liver geltabs for omega 3 my dry skin left. I mean left! I hardly ever moisterize any more and only take the cod liver tabs a couple of times week because my face got too oily.

I've been on abx for years too.

Just my experience.

I hope it is this easy for you.

I've taken the fish oil in the past but dropped it because I was always burping up fish!

Which is worse tasting fish all day or being "scaly" like one!!

especially tetracycline.

maybe try switching abx and see if it goes away (i had good luck with biaxin/plaquenil as far as skin goes), and maybe ask DR to add nystatin for possible yeast.

i also take probiotics, and try switching brands from time to time.

recently i have been liking the products from kirkman labs.
