Hello, I'm a 23 yr old, male. 6ft 205lbs. No previous medical condition. Two days ago I was involved in an altercation where I received a black eye, and tender head. Yesterday I started to notice that my right side was hurting really bad, the area of the pain is exactly 9 inches from the center of my belly button to the right. The size of the area with the pain is about the size of a fist, lol, maybe a little bit larger than that. It hurts really bad when I press on it, it's really tender. Yesterday and also today there has been time's when I thought I was going to vomit, but never actually did. My appetite isn't to grand but I have eaten. I also been belching alot. Does this sound like an organ problem, gallbladder, apendix, liver, or more likely sore from maybe the altercation and a punch to the right side?
