Hello Dr. Rynne! I noticed two days ago, purple, very dark purple, but a thin vein at the skin of the scrotum - the left side at the top of the scrotum (not on the testicle). This vein has a length of one inch (max). Is this clearly the varicocele, or I should not worry? It does not hurt, does not itch, does not swell - I do not feel discomfort, apart from a slight stress. Please reply. Thank you and best regards!
