That is just horrible how they treated you!!!
especially after you telling them about your condition.
just makes me want to scream.....

Can you stall on paying for that??
in case there is complicating factors from it?

so sorry -
that just proves how uppity drs and staff can get - thinking they know it all and not listening to an informed patient! {my vent}

I do hope you come through this with out any lingering problems and that the nightmare of the treatment by them will fade.
