What could a red welp about the size of a quarter that appears iny elbow and then it goes away in about a week and then comes back and it doesn t hurt if you touch it but it feels weird and Sometimes itches and when it goes away there is still a little spot like a scar
Hello, Elbow is not a usual place for pimples to develop, however, this might be dermatitis herpetiformis or even acne. However, a photograph of the affected area will help more. Sometimes, gluten-free diet might help disappear this itchy welt especially when dermatitis herpetiformis is confirmed. So to my opinion should consult with a dermatologist when the welt appears. Hope I have answered your query. Let me know if I can assist you further.
