Broke mine last year.Was off pain killers after 2 days to help the healing.
Think mine aligned into a good position so kept quite still for 2 weeks to help the healing. Couldn’t wear a sling too much – didn’t feel right (Everyone is different I guess)
However SBZ gave me some invaluable advice – regularly make fists and circle your wrists – also bend and flex the arm in the early days and sleep without the sling if you can.
Good physio advice early on is a great help – don’t wait a few weeks for an NHS appointment or everything will have stiffened up. Good luck!
