Does anyone else have both FMD and TAA?

Aloha,
First time visitor here. I was diagnosed last month with ascending aortic aneurysm at 4.0 cm, and FMD (fibromuscular dysplasia) in the left cerebral and vertebral arteries with no aneurysm or dissection. I don't have any symptoms except occasional light headed when hiking hills or sitting to standing too fast. My BP always runs low. I will be seeing a vascular specialist soon. As far as exercise I'd love to be able to continue pickleball and don't see much mention of that sport here. Appreciate your insight and feedback!
