Ive been training hard for about 2 years now, been growing/gaining strength steadily. Back in august, I noticed I slight pain in my sternum when Id try to do dips. After a couple reps, it would go away so I didnt think anything of it.
About a month and a half ago - if Id try to do a dip, at the bottom of the movement when I would try to push back up, Id get a searing pain through my sternum. It wasnt an excruciating pain, more like a 2 or 3 on a scale of 1-10, but enough so that I knew something wasnt right.
Sometimes in the morning I hear a snap or crack in my upper chest when I move, right at the sternum-clavicle joint. No pain, though.
After that, I figured that Id better stop all chest training until it healed up. Three weeks without any chest movements seemed to fix it, but then my truck broke down. When I went to push it, I felt it 'go out' once again. Another two weeks off, I felt fine. Decided I try to work out light and did a couple sets of flat bench at 135x30, and some bodyweight dips. No pain at the time, two days later it and hurts again.
Obviously, I just need to stay off it until it feels 'fixed' and then stay off for another 2-3 weeks until its completely healed.
My question is, what the heck did I do to myself? From studying anatomy books and researching on the internet - it looks like anything from a stress fracture to a pulled tendon to a muscle tear.
I asked my doctor about it, and he didnt really have much to say, just that if the pain was associated with movement it was a muscle issue and not a skeletal issue. It does not hurt at all if I apply pressure directly to my sternum.
Well, any advice on the matter would really be appreciated.
