Yeah...well I was working out in my baseball class. We were doing 4 sets of 5. I had increased weight from the previous lift. I finished all my sets and reps almost failing on my the last rep of the last set, so I was set. Had a successful bench that day I had thought. Well as I got up I felt a sharp pain in my right chest., like right where the muscle begins. It didn't feel like my muscle was sore or cramped, just a sharp pain. Well the next two days I came in and did my bench, but the sharp pain came back as I was doing my lifts. All of a sudden I just snapped and failed completely on my 2nd set. But like the pain wasn't any worse, it was the same constant sharp pain. It doesn't feel like in my muscle, feels like under it. Anyways...I benched today..and I could barely lift my normal weight. I had to take 40 pounds off, and I still struggled with that. My chest doesn't look any different. So..I honestly don't know whats up but I'll see a doctor ASAP. Thanks.
