My husband is 34 and has had a lump in the crease of his right leg and groin area for the past few months. It changes size from time to time and can be painful too sometimes. But today he has not checked it lately and when he streteched while laying down he felt a sharp pain down there and low and behold he was bleeding and saw a b b shaped hole where the blood was coming from. The lump was sore and the area was soft to touch. What is this lump and what would cause it to burst a hole like that and bleed? Mind u this area has no hair so he has had no need to shave there and we both know its not a boil or ingrown hair.
