From the symptoms the possibility of cold sores is there.
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.
Treatment includes antiviral drugs like acyclovir along with that you can take simple measure like Keep the affected areas clean and dry and if you do touch the sores, wash your hands afterward. It is especially important to avoid touching your face and eyes after you touch your sores and do not use any creams or ointments on sores unless prescribed by your healthcare provider.
Cold sores are caused by the herpes simplex virus. The first symptoms of cold sores may include pain around your mouth and on your lips, a fever, a sore throat, or swollen glands in your neck or other parts of the body. Treatment may include skin creams, ointments, and antiviral drugs like acyclovir. Hope this helps and take care.
