My blood pressure also spikes late in the day, and I can have very low blood pressure in the morning. It’s like I’m over medicated and under medicated at the same time depending on my position. All signs pointed to renal artery stenosis, but like you, no further proof. I wonder if something like this could be intermittent? It’s so baffling to show such a severe blockage multiple times using one study technique and then a nothing burger upon further imaging.
