I am a 16 year old male. I have a small lump like are on my crotch near where my groin and leg meet. It seems maybe half the size of a pea. At first, I thought it was a zit, but it seemed like a zit that was already popped. I took a shower and tried squeezing it. It came out a bit more, but remained solid. The only fluid that came out was blood. Not terribly much, but it still freaked my out. I tried applying pressure to the area, and it seemed like it went back in. What could this be? I tried doing some research, and all I've seen is things about an inguinal hernia. But it seems too low for it to be an inguinal hernia.
