I am a 24 years old male and two years ago I bite down on my lip and it started swelling and I never went and got stitches for it. It then healed up and after two weeks bumps started appearing on my lips. The bumps started opening more and more. It would eventually have pulse come out of it and the skin would start peeling finally. Eventually I would see the blood oozing and then it would began to heal. This happens to me every two weeks and then it vanishes for two weeks. I have been to several doctors, but this keeps occurring. The medications prescribed is not working. Please advise the name of this illness, the medications that will help me and how long will I have to suffer with this? Thank you very much.
