lump and popping sound in my sternum?
Several weeks ago, maybe a couple months ago, I hurt my chest a bit from a barbell resting on my chest for a couple moments when doing bench presses (unintentionally of course). I didn't think much of it at the time, but a little while later I developed a hard lump at least a couple inches below the top of my sternum. I'm about 90-95% sure the lump was from that incident with the barbell. It's not too visible, but you can definitely feel it. I got this before, a few years ago, from being punched in the chest but it eventually went away.
This lump however has not gone away. And yesterday I was lying on my couch and doing something, maybe stretching, and suddenly heard and felt a loud pop coming from that very area. I can't remember if the pop itself hurt, but it hurt immediately after that when I would do things like stretch or position myself in a certain way, and of course something like a push-up hurts pretty bad. It doesn't hurt quite as bad now, but I can sort of feel the pain if I move my upper body in a certain way, and something like push-ups are entirely out of the question. I hadn't done any exercising or intense physical activity yesterday.
Any idea wtf this is? It's kinda freaking me out.
