Hi, I'm new here and this is my first post. I am a white, 30 year old male, and I noticed that between my leg and my groin area there was a swollen dark colored bruise like thing. When I squeezed it, it oozed out blood from a tiny hole like if it were a pimple. After squeezing it until no more blood came out, it had shrank a great deal in diamater and the swelling had gone from protruding to a slight bump. Anyone have any idea what this could be?

Thanks,
Valduran
