Being a viral infection, it is self limited; however is known to recur nastily. You have to report either to a Gynaecologist or to a STI Consultant for confirmation and management. In acute phase, some antiretroviral medicines may be useful.

done as this infection is frequently found in People Living with HIV.
You should follow sexual abstinence while this infection is active. Utmost sexual hygiene is very important to avoid the recurrence and flaring up of the infection. Since you are having it on the mons venerum, barrier protection like condom may not be providing any protection to the partner.
