The appearance of blisters, warts or any other types of growth around the genital region always raises doubt on whether or not this is in relation to sexually transmitted infections.Genital blisters
are usually associated with herpes
, whereas, warts and similar growths are associated with human papillomavirus
But these are all just assumptions, and what you hae could be totally different from what actually is suspected. I would request you to visit a doctor for a physical examination especially as you are experiencing discomfort and other symptoms.
Hope this helps.
