Since the rash is red and itchy and present for many years it can be due to eczema skin. You can take some OTC oral antihistamine medications like Benadryl or Claritin and see if it helps. Also Use good quality moisturizers to prevent moisture loss from the skin.
Application of steroids is also helpful but it needs prescription from a dermatologist. If the symptoms are not subsiding by antihistaminics, then you need to consult a dermatologist and get steroids prescribed and other possibilities ruled out. Also check out these watery blisters for herpes sores if they scab over.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
