a week ago i felt a sizzling sensation on my lower lip line and when i looked in the mirror i saw an abrasion and that my lip was swollen right above it. the abrasion is healing though still red and crusty. the swolleness is gone. what could have caused this? thank you.
HI, thanks for using Chat Doctor It is likely a cold sore. You may not recognize the initial infection, but it is very common. It would normally start with discomfort or abnormal sensation in the area. This is followed by swelling and a rash (this can vary from one person the next). The area then heals over as described. The repeat infections can be provoked by stress, illness, citrus or other acidic foods, fatigue, sun exposure. I hope this helps
