For over 10 years I have had a chronic case of dry, itchy,rash or hives on the back of my left thigh. I have seen 3 dermatologists and each repeats what the other did as for as medications and scrapings for testing. I just discovered I now have H Pylori and have taken the triple antibiotic regime and now am on flagyl . Could these 2 be related? My dermatologist says I have a viral infection/herpes which breaks out in wet welts and also a fungal infection which remains dry until scratched and irritated. What can you tell me or suggest?
