About 5 years ago I went into the hospital to have knee surgery. I never made it into surgery because I had a very violent reaction to the anesthesia. In fact it flat-lined me and I ended up in intensive care for a while. After I got out the surgeon, anesthesilogist, and hospital were all very concerned and nice. Considering the number of lawyers who contacted me I can guess why.
I felt that it was an accident and not a problem of neglect etc. and never did anything about it.
This weekend I received a bill from the hospital. They want me to pay for the anesthetics. (I am not making this up.) I'm thinking about telling them I'll pay the bill if they admit their negligence in giving me something to which I was allergic.
