Welcome to the forum, my first question is how many drs have you seen for these issues in the last 2 years? Have you seen a neurologist? they are the best ones to ask why and what do I do now? Have you been tested for Lyme disease, different plants, trees, meds that could cause a steroid resistant rash? Staph infections can look like a rash and require IV antibiotics to get rid of. That's my suggestion, oh i almost forgot food allergies! i have those, gluten, dairy and wheat, the wheat makes me break out in a rash but I've never has steroids for it. Can't take 'em they make me violent, my short term memory comes and goes but supplements Really help. Magnesium Malate, Ginkgo Biloba, Vit D and Potassium and Dark Chocolate(I get to eat it for breakfast
) so hang in there and keep in touch, both of you
