HI, This sounds more like school sores but whatever it is I would go to the DR
How are you? Are there other symptoms present? Try to avoid scratching to prevent secondary bacterial infection. Cold sores usually present with fluid-filled blisters that become covered by scabs. Aside from allergy and infection, it can also be due to irritation and dermatitis such as perioral dermatitis. Refrain from applying anything including medication at this point. With irritation or allergy, the symptoms usually resolve after after a few days of removing the offending trigger. If it persists, check with your doctor for proper evalaution. Direct clinical examiantion is important. Take care and do keep us posted.
