Well, Mom was in the ED for over 6 hours last night.
They did an EKG, CT scan, a couple of chest Xrays (why one, let alone two?? Something about looking at her heart), blood tests, urine tests, more blood tests, and LOTS of blood pressure readings with continuous pulse oximetry. And after all that, to her understanding, she was OK. They said that they couldn't be totally sure about any brain bleed unless they did a spinal tap. And Mom, knowing that it could make her persistent headache much worse, said "Nope. Lets call the testing done." They forgot to feed her (but eventually got a sandwich) and after the warm blankets she didn't feel too much like a popsicle being scrutinized in a tiny room with with crazy bright florenscent lighting. She said everyone (but one guy) was so sweet to her and she really felt well cared for. Thank goodness for that. I take it personally when the place I work doesn't do a stellar job in caring for any patient--let alone one that's my mother.
So, now I hope that the darned headache (and generally yuck feeling) goes away and she's back to being her chipper self.
