Ok, I need to join the chorus! Please get the tag!
I think one needs something like a minimum of 30% reduction of mobility to get one? At least that's what I remember. A friend of mine had several of her vertebrae fused by surgeries and was in so much pain and could not get one. The doctor has to sign some paper work to get the ball rolling and in her case she was at 28% and her doctor would not sign off.
Rockporter, it is time to be kind to yourself. Don't let those bullies win. Don't have a heart attack b/c of those jerks. Your family needs you here. ((((Hugs))))
