I hurt my abdominal muscles when I was participating in a sport. Felt like I tore something in the lower abdominal wall mostly on the right side. When I took it easy for a few days, it dissipated. I played again and they hurt again. Now I noticed that when I pee, it hurts a little. I definitely don't have an STD. I either have a bladder infection of it is related to my abdominal injury. The injury was a result of a strain not a blunt impact. I am a 45 year old guy.
