Hello,
From the symptoms it can be Allergic contact dermatitis, cheilitis or herpetic sores. In herpetic sores, Pain, burning, tingling, or itching occurs at the infection site before the sores appear. Then clusters of blisters erupt which break down. You need to get some investigations like sample from the sores to identify the virus, culture analysis, Tzanck smear, antigen and antibody studies and blood sampling for antibody studies done to confirm the diagnosis. My sincere advice would be to consult a dermatologist.
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 dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Also....it gets really itchy....and the only thing I do to relieve the itchiness is apply ice for about 5 minutes...but the itchiness comes back...If I scratch it though it seems to spread..
