ever heard of muscle tearing from blunt impact?
Similar to how a boxers face splits when punched...
Bit of a 1/1,000,000 chance but some beta dove on me (as i was diving too) and im guessing his knee landed square on my calf. Physio says its torn, indeed hurts like hell, esp at night when i bump it or change position
edit: playing rugby, (scoring, of course).
Double edit: im color blind and really poor at seeing bruising but from what i can tell can see no bruising. But im talking 8/10 pain (8 days later now) and it wakes me up a few times every night
triple edit: alcohol makes me able to walk and dance with it. Mass regrets on sundays though
