I got punched in the ab and lower abdomen area. i'm having some pain and i'm curious if it's internal bleeding but i just worked our 2 day ago (abs)?

Not likely, but...: Being punched in the abdomen can be very dangerous, of course. It can injure your liver or spleen, or cause bruising on bowel. Most of the time, the pain is just from abdominal wall bruising (made worse, possibly, by working out). However, severe pain, bruising, swelling and/or nausea should cause you to go to the ER to be evaluated by an expert.
