Well you might want to make an appt and get a blood test for herpes, at least to rule it out. Ask for a type specific IgG test. When you are there, explain what is happening to your doc, and ask if you can be seen the same day the next time this happens.

Its strange. Tried cortizone and had no affect. Being that it is random and does not last long, by the time I get an appointment it is gone.
I have no idea. Its not typical of any std or fungal infection.
Have you ever let a doctor see it? You should.
