If its your actual rib, your lucky
If its your intercostal muscle that's ruptured, it'll take much longer. I ruptured my intercostal after a inadvertent kite loop wrenched my wait for it.......Mystic Firestarter harness right up not the bottom of my cage. Felt a sickly popping sounds n realised there was something wrong. Trying to body drag back to shore and land kite was excruciating.
Back on water cpl month later in board sort harness. ION B2s are good. Was still in pain for several months afterwards, and still have the "golf ball", lump to show for my efforts. Also hurts when using waists harness after a while and that's over 2.5 years later
