The problem is, since yesterday I have a bad pain in my chest.
It has been hurting my back a bit , but I know that's just aches from streching more than usual.
The pain in my chest is still there today right in the middle, above my abs and below my pecs, it feels like theres a lump there, it hurts when I jump or breathe in deep, and also today I have a sore throat and a bad cough. I'm worried that the compression of my ribs and upper body may have damaged something.. any ideas?

I don't really want to go to the doctors, I don't really have a way to explain how I did anything! Well doctor, I cracked my rib by..uhh, trying to do a backwards roll?
