Talked to my kidney doctor yesterday and saw my general practitioner today, and they both concur that it's a good idea for me to check with a doc who deals with FMD a lot. I spoke to an assistant for the doc who's written more on the subject than anyone else, and have emailed him my medical history. He's supposed to look it over and his assistant will get back to me regarding one or more appointments. In the meantime, I'm waiting for results of more blood tests, and I have duplex ultrasonography scheduled for my carotid artery and an echo cardiogram just to make sure those things are in good shape. And I now have written permission from my general practitioner that will allow me to go back to work, since my company wouldn't accept a note from my kidney doctor. I still have moderate abdominal pain, but work isn't supposed to make my condition worse, so I'm hoping to last the whole day. Work is good!
