thanks for your query
As per your description, it appears that it could be Herpes
occurs via inoculation of virus into susceptible mucosal surfaces or through small cracks in the skin. People get herpes by having sex with someone who has the disease. “Having sex” means anal, vaginal, or oral sex
.Transmission can occur from an infected partner who does not have a visible sore and may not know that he or she is infected.
Although the infection can stay in the body indefinitely, the number of outbreaks tends to decrease over a period of years.
You can take some pain killers and use anti-viral ointments
locally which may help.Warm baths can also relieve the pain caused by the bumps/blisters.
I hope this will help
