Good news it's not a break.
I was lucky in my playing days with injuries but did have a badly bruised sternum in the first minute of one game.
The intial impact felt like my upper chest and breast bone had exploded I played on for the rest of the match but by the time it had ended I could not even bend down to take my boots off and I was off work for 2 to 3 weeks and it was a few weeks after that before it was healed properly.
I distinctly remember the nurse who took the xrays saying it's only bruised you soft wuss,I thought you rugby lads were tough
did i feel
yep.
Quickly recovering I remembered the old joke and replied.
"Well I was told today that I was going to meet a beautifull women and a grizzly old rugby player", pausing for a moment I asked "so which position did you play love"
The rest of the examination was rather aggresive from the lady in question.
