So I had my follow-up appointment today in order to go over the results of my MRA, MRI, and blood work. The good news is that nothing bad was found. No signs of aneurysm, blood clots, kidney problems, liver problems, etc. Nothing like that was found. The bad news is that the cause wasn't found either. The doctor referred me to a neurologist and a 24 hour urine test (more on that later) and a stress test. Let's hope it's multiple choice and not essay.
The urine test is where I get to pee in a jug for a full 24 hours, yay! I don't have to urinate for 24 hours straight, just collect all my samples for 24 hours. And now the really good part, I get to keep it in the refrigerator. Right next to all the blood I've been saving I guess.
