Hello,
It is very unlikely for a cold sore to behave this way. For this kind of rash angular cheilitis and any infected hair follicle or abscess formation also needs to be ruled out. Angular cheilitis is found at the corners of mouth which are caused by infection. Dry out the lesions completely by patting and air drying after washing with a mild soap. If the symptoms persist then please consult a dermatologist as oral antimicrobials may be needed.
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.
