Hello and welcome to HCM,Herpes simplex
infection is characterized by multiple fluid filled painful vesicles on the genitalia.
Genital lesions are caused by HSV 2 mainly, however, HSV 1 can also cause genital infection
What is the site of the cold sore?
Was it present on the genitals?
Cold sores are characteristic of syphilis
Get a test for syphilis.
Herpes simplex infection is suggested by appearance of vesicles.
If infection appears, antiviral
treatment needs to be instituted.
thanks and take care
