Prop falls on you. Owie!!!! (Let's assume the worst...)
Ambulance is called. You get the stretcher treatment, a nice ride, an ER bed, MRI and/or Xrays, bone setting or relocation of the joint you popped, and then discharged with lots of paper, and a few R/x's.
Call your Agent. It's that simple. If they won't help you, they suck. (Hell, if I were "in charge" I'd have commission be based on how well the Agent gets your Medical Bills paid.)
Also, you'll have to probably pay at least $100 to the ER. The Ambulance bill will come separate. Your insurance company might want copies of everything, so be prepared. Keep a file. Organize.
This is the easy one to deal with. One incident, one date to remember, one, maybe two service providers.
It gets ugly once you start PT...
