I've competed numerous times with injuries.
I've had your basic broken fingers and toes,
competed with torn acl,
tore the tendon in my calf,
dislocated shoulder---> i dislocated my shoulder in practice and instead of telling anyone and risking not being able to compete I just slammed my shoulder into the wall a couple times.
competed with three broken ribs, fractured foot
calcium deposits in both wrists, broken elbow (partially healed)
and some other stuff.
BUT
by far, the most excruciating pain I have EVER felt was when I competed with torn abs. I have NEVER felt pain like that before in my life, and I seriously suggest no one try that. lol.
