Flo I hope your husband is doing OK !

My dad used to fall all of the time and it normally took neighbors to help him up but once my mom called my sister in the middle of the night to help get dad up, my bil who was an EMS at the time called for an ambulance to help get him up, which was a good thing because he had broken his hip, even though as he laid on the floor he stated that nothing hurt.

My bil stated most people do more damage to a fallen person by trying to get them up without professional help.

Maybe tell your husband that next time he falls when doing something he shouldn't, that you'll call for an ambulance to help him up, that might make him think about whether he's putting himself at risk to fall by the task he's doing.
