1. Am I at an increased risk of transmitting HSV2 to him when I have palindromic sensation? For me, it’s a clear, sudden tingly sensation in a random area of my vulva or anus. When I had weekly outbreaks, I would always get an outbreak wherever the sensation was starting the next day. Now, there is usually not an outbreak, just the sensation.
I think you mean prodromal symptoms, yes? If you were my patient, I would swab the area where you are having the symptoms, when you were having them. You can get a herpes swab test at 24/7 lab sent to you and do the swab yourself. If it’s positive, then you can know that those symptoms represent viral shedding. If not, I would do maybe three more swabs and if all negative, that doesn’t represent a period of viral shedding
2. What is the risk of a) passing HSV2 to his penis if I were to give him oral sex, and b) passing it to his mouth if he were to give me oral sex?
Well, the answer to that depends upon whether the sore in your mouth was HSV 2. Did you have it swab tested to know that? If he gives you oral sex, he could get it on his mouth but that is unusual. There are special panties now that someone can wear to reduce the risk of transmitting to the mouth of a partner – research it online
3. What is a typical prognosis for people with severe herpes? My doctor said she has never heard of someone like me, which made me feel a lot worse.
Normally, 1 gram of Valtrex will reduce both viral shedding and outbreak frequency greatly. And in cases like yours, I always do swabbing to determine if everything you think are outbreaks actually are. You could also do 500 mg twice a day to get a little more consistent coverage during the day from the meds. Same total dose for the day
