A lot of the time when I'm doing bench press or something similar to that I get a bad chest pain when I try to get up. It doesn't happen while I'm working out, but right after I'm done with my reps and I try to get up off the bench it feels like my chest is caving in or something. Like a ton of weight is being pressed into my chest cavity. I don't know if this is normal or not, but it usually only does it when I do heavier weights.
