I've been experiencing chronic rashes which start on my stomach right under my breasts, sometimes it's localized there but now I have red itchy bumps all over my legs and right arm, back and chest. The bumps are tiny, red and raised, they never scab, ooze or come to a head. The rashes come and go and vary in severity but it always starts on my stomach and under my breasts. I can't pinpoint a cause. I use the same detergents, lotions and soaps and seem to have rashes and not have them while using the same products, so I don't think its those. Could this be caused by a food allergy? I have hypothyroidism and have read about others having the same unexplained rashes.
