I've had this for 4 years. This got so out of hand that I tested negative for herpes twice. I found relief by accident. My reasoning was the itching was caused by inflammation. So I used voltaren gel and it seemed to work. It stings in the beginning but after a few days I feel much better.
Hello,
For your eczema, You can apply some calamine lotion at the rash as it will help in soothing the skin. You can take some OTC oral antihistamine medications like Benadryl or Claritin and see if it helps.
For mild-moderate eczema a weak steroid may be used (e.g. hydrocortisone as dermacort), whilst more severe cases require a higher-potency steroid (e.g. clobetasol propionate, fluocinonide) which are available under prescription. Eczema can be exacerbated by dryness of the skin. Use good quality moisturizers to prevent moisture loss from the skin.
If still the symptoms do not improve then please get a clinical examination done by a dermatologist. Mostly it is a combination of treatments that is effective for eczema. 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.
