Doing dips the other day, on the last rep, I went a bit too low and I think I might have 'strained' my pec muscle. For about an hour after the workout, there was a sharp pain (though not intense) when I would move my arms or twist my torso in such a way that would stretch the pec muscle. The pain is in the right pec right where it 'connects' to the sternum... it is towards the middle, vertically, of the muscle.
The pain eventually subsided, but then today I was moving a piece of furniture at work, and I felt it again. Same deal... would hurt if I stretched the muscle but not necessarily if I flexed it. This time, though, it only lasted for maybe 20 min before I couldn't get it to hurt no matter what I did with my arms or torso.
Tomorrow is *supposed* to be chest/lat day. But I am going to skip chest and make it a lat/bicep day.
Any idea what may be wrong? I'm not worried as my instincts tell me it's just something minor.... but I figured one of you out there would have had a similar experience and could maybe tell what was going on exactly.
