I m in the process of getting a root canal ... waiting for the crown to come in. It was on tooth #9, top left tooth. My upper lip was swollen tremendously, but have been taking antibiotics for 5 days and pain pills. The swelling has gone down and the pain is almost gone. However, there is a lump or knot that is hard, but under the skin right under my left nostril. What is it?
Hi, It seems that you might have abscess on root of upper tooth giving swelling and pain. Now due to antibiotics abscess is resolved leaving some induration and swelling on the part. Continue with antibiotic for more 2-3 days. Apply ice pack daily. Before application of crown make sure that abscess I'd completely dissolved. Ok and take care.
