Hellow Trishia,
Its been a year now so I should imagine your black spot is like a watermelon by now.
It must have been very worrying to have a black spot on your scrotum grow from a pea to a golf ball in just a week!!
Its good to see you did something about the problem though by posting on this forum to ask for advice. Health first eh Trishia.
Anyhoo, I just wanted to show my support and say "She'll be right m8".
My friend Logan has a very itchy scrotum. Maybe you could email him?
Best regards
