I have a bump on my inner thigh under but not at all connected to my scrotum. i don't think it's a cist because theres no white dot or anything, and its not round, looks more like a wrinkly bump, its about the size of a nickel now, used to be quarter sized. it's already "popped" once before and gave off a foul odor along with a thick blood-like liquid. ive had it for about a week now.
