question: I am a 59 year old female with diabetes and several health issues. About 2 months ago I had a bottom tooth on the right to abcess. In a day my lower right lip and chin became numb. I was put on Kflex and the tooth was pulled about a month ago. The lower right lip is still very painful tingly and itchy as well as the chin. Often I have severe shooting pain this that area. What could be the problem?
