This is a bit embarrassing but I think I pulled a muscle in my groin putting my pants on this morning. I've been having a lot of pain in the groin/pelvis when I walk, and today I lifted my left leg and felt this terrible stabbing in the muscles. Now I can barely lift my leg, I just have to kind of shuffle when I walk. It feels like my belly suddenly weighs 50 lbs. I've also gotten a nasty pain right below my sternum twice while sleeping. It wakes me up in the middle of turning over and it feels like something is ripping. It lasts about a minute, then goes away quick.. It's not tender. Anybody else felt this way?
