I have been having a very odd situation over the past 3 months. I have been waking up with an UPPER swollen lip. Has happened 5 times in the last 3 months. I have not changed anything, detergent, soap, toothpaste, face cream, etc. I went to an allergist and tested negative to all tests. I also have been getting a red ring around my mouth and have NO IDEA why. What can I do to get rid of it ? What type of doctor should I go see? can I take an antibiotic?
