This is weird...I was just thinking of you and your sister. Then you posted. OOOOOOO, what a coincidence!
Anyway, glad your sis is getting the correct med for her situation.
On the other hand, drs and their staff can say the opposite of what they mean and not even remember it. I have to tell this story....
A few years ago this incident happened in my OB/Gyn' office. While my vitals were being taken another nurse ushered a woman past me and into an exam room. She was told to undress from the waist up and put on the paper gown and the dr would be in in a bit. The lady (in her 60's or 70's) questioned the instructions. And the nurse repeated herself (undress from the wast up and please wait for the dr). I figured the lucky woman was not here for a pelvic exam.
A short time later, I was in an exam room (across the hall form the woman's exam room) wearing my nice fashionable paper gown waiting for the dr to come in. I heard the dr enter the room across the hall and greet the woman. Then a stunned comment to the effect that she had undressed from the waist up and not the waist down. The woman said this is what the nurse had said to do and that she had even questioned it.
In short the whole office had a laughing frenzy.
Even the patients. When the dr and nurse came in for my appointment, every time they told me to do something I kept asking "are you sure?" That visit was definitely the funniest drs visit I have ever had!
Hope you enjoyed that! Here's praying that your sister get to feeling better.
