I thought I had somehow infected my upper lip. My P.A.
put me on oral antibiotic and a cream antibiotic. The condition worsened.
I was finally able to see my dermatology [someone who actually went to Medical School!], he told me to stop both forms of the antibiotics what I had was an allergic reaction to something.
After searching to see what, if anything, I had used to cause this painful response, I narrowed the culprit down to the one change I had made. I had started to use a sample of Sensodyne Pronamel that I had gotten from my dentist.
After treating with Topicort and taking antihistamines the condition is getting better.
