Breal, first of all, congratulations on being a former smoker! Granted, it is only a few days, but the journey starts somewhere, right!
Secondly, I have several suggestions. I suggest you go back and request copies of your pathology reports, all the way back to your first pap (or the first pap that came back with a problem). The pathology reports tell what type of tissue was taken, if there was enough tissue for the tests, the specific names of the results, and generally gives a recommendation for treatment.
It sounds like you actually might have two different things going on. You have had a history of vaginal infections. Those infections could have been (or are) bacterial, yeast, or fungal. Each has a different treatment. Were you ever checked for bacterial vaginosis?
What type of doctor are you seeing? a ob/gyn? You might consider looking to see if there is a gynecologist (not an obstetrician-gynecologist) who specializes in vaginal infections. He/she might have a more effective way of treating the problems you are/were having.
Given your age, it is likely (if you are other wise healthy, and you remain a former smoker) that your body could fight the virus so it no longer causes problems in your body. Since you were a smoker, it may take your body longer than the generally assumed length of time for your body to do this (of several years). It is important that you get repeated rechecks to document the changes (or lack thereof) in the cervix. Generally, retesting every 3, 4, or 6 months is ordered, for several years.
When it comes to the itching of the vulva, vagina, and anus, I suggest you specifically ask your doctor about your concerns. Ask if he/she will do the colposcopic examination on those areas. The way I understand it, doctors don't normally look at those areas during a colposcopy, but that they can be done.
Finally, go to your doctors' appointments with written lists of questions. Leave room to write answers.
I hope that helps!
