So, i started to have symptoms on my penis after a sexual encounter 1,5 years ago. I have this rash - little red bumps that appear together on the same spot recurrently. They look little scaly, but they are still pretty moist (due to the mucosal membrane location?) - from my own examination it could be psoriasis.
I have had STD tests done, and they have been negative. I have suspected genital herpes to be the case from the beginning, but i have had 3 negative blood tests during this time. I had moderate leg pain in my legs when these symptoms first started, and that i assumed to be nerve pain from the herpes infection. And when the rash recurs, always to the same spot, i feel mild sensations in my thighs, joints behind knees and even in feet and toes (rarely even heels). There hasn't been any swelling or difficulties in moving my legs though, just sensations - so i don't know if it would classify as an arthritis exactly.
But have started to think if these symptoms could possibly be due to psoriasis. Genital herpes would be a possibility, but 3 negative blood tests and the rash being not that herpes-like in appearence would suggest something else.
So, would it be possible for genital psoriasis to be triggered by a sexual encounter (as a reaction to infection, inflammation, friction etc.) and to present itself only in one particular spot on penis mucous membrane? And could the mild leg sensations that usually accompany the recurrences be caused by it?
I've noticed that friction seems to make the rash recur (which to my understanding fits again both, genital herpes and genital psoriasis)
I have an appointment for a dermatologist and i'm not trying to get a defnitive diagnosis here, but some insight would be welcome.
