Sudden blisters/bumps on right side of groin and close to scrotum. any ideas?

started feeling a sensation a few days ago which has progressed into this…
spoke to the GP over the phone with photos and they think its herpes.
Though i havent been sexually active for over ten years, so im not sure if its actually herpes or something else. Doesnt feel itchy although feeling a little burning sensation.

this has took me by surprise as im normally very healthy and never have any problems especially with rashes, virus etc.

they given me a course of aciclovir to take and ive been applying some anti fungal cream as i thought it was jock itch to begin with.

any help appreciated !

yes, this looks concerning in regards to herpes. I would recommend you see a primary Doctor as soon as possible for a SWAB test.
