What the purpose for an answer machine? Your are a spy person and guess what ,when the hospital said they sorry and they screwed up telling me this on the letter,well in that case ,I will sue you.You should put her on the cat scan on the very first night ,you should scan the whole body and notice if it something like a blood clots!It may be a blood clots,you should give her vitamin B-12 and warfarin by mouth, NO,YOU DIDN"T DO THAT, BECAUSE MEDICARE AND HEALTH INSURANCE WON'T COVER THAT ?! YOU WAIT A WEEK LATER , PUT HER ON IV AND IT WAS TOO LATE! SHAME ON YOU TO DO THAT TO THE OLD PEOPLE!!!
