Oral or something else?

A few months ago (five), I got drunk and shared a cigarette with a mildly shady looking character. He offered it, and I usually do not turn down friendly offers. Roughly two weeks later, I noticed a tingling in my mouth, and I developed red sore spots (not quite sores) in the corners of my mouth. In the five months since then, the top tips of my lips (right under my nose) have been slightly swollen. I have a constant, slightly irritating redness around the corners of my mouth. Also, one cheek of the inside of my mouth is white and flaky. And I have lots of small red bumps on the inside of my lower lip. With the exception of the periodical tiny red sores in the corners of my mouth, all these symptoms have been constant and completely unchanging for the past five months. I would think oral without too much deliberation, but then the fact that the virus (if there is one) doesn't come and go, or go into latency, or do anything but produce constant mild symptoms.
