Hashimmottos / percinicious anemia

LAst year 1/2 ago  I was Iron deficient to the point of passing out-- been taking Iron daily since--  I have had issues with my thryiod take meds for that since late 20's now 43. I recently found out I have gerd and percinicious anemia. I have been on the b12 shots and sublingal suppliments since july.  I also suffer from adult acne take antibiotic bactrim ds for that as well as have rosasia.  Now just recently started I started getting a rash on my stomach and legs.  I am trying to see if its an allergy to detergent or something but could this be a symtom of something else. that I should be looking into.  Also could the combination of symptoms be something else- that my doctor is missing?

Hi!
If you have Hashimotos thyroiditis or an autoimmune thyroid disorder then yes, you can get a rash because of this. Also, if you have H. pylori infection (likely if you have GERD, then also you can get a rash. Rash can also be due to other autoimmune disorders such as lupus.
Rash can also be due to urticaria. Urticaria is usually triggered by allergens, such as drugs, foods, insect bites, inhaled substances, in response to sunlight, cold, heat, stress, exercise, or a viral infection. Other common allergens are pollen, mold, dust, pet dander, or cosmetics. Usually there is an itch.
Itchy rash can also be due to fungal infection. Do discuss this with your doctor and get yourself examined. Take care!
