I'm not a doctor, but itchy skin can be an allergic reaction to meds. I had a similar reaction to a pain pill after surgery and you might want to consult your doctor to see if you are allergic to something.
Just so you are aware, 80% of the us population has been exposed to HPV. If any man has dated at least 2 women, odds are he has it as well.
I would just continue to get your annual pap smear to keep an eye on it. You may want to start the conversations about, "did you know" that 80% of the population has HPV and 20% has Herpes? I don't know how old you are, but if he's been with at least 10 women, he's probably been exposed to both diseases but may never develop symptoms.
