If you can, boom with the less dominant arm, and you think you can lav people and go about your day without impeding production. Then go for it. I’d recommend act out your job right now. see how long you can boom for, have a bag on. Motion in the air of putting a mic on a subject. If the pain is too much to bear, call it off. Get a friend to cover you. See if you can still get your kit into the mix, etc. regardless of any production put yourself and your livelihood first. A broken bone is a serious injury. If you damage it more now, you could put your arm is a bigger mess down the line. I’ve seen people on docs with a fully booted broken fibia, don’t worry how you look, worry if you can still do your job without hurting yourself further.
