At 67 I had a PAE done. I requested no anesthesia because I wanted to watch what was going on via the screen.
The only discomfort was when they use the dye to identify the right pathway, it is a very warm sensation. Feels like you are peeing on yourself. My wife drove me the 2 hours home, and although I could have, it was just much easier relaxing, as Houston traffic is a pain even without a PAE! Nothing afterwards, just a little lump where they made the insertion. That lump will disappear in a few months, it's the artery bandage, if your IR goes through the femoral artery. I got no relief from this, or very little. I still had to take 2 tamsulosin just to pee 6 times a night. A few months ago I got an aquablation and still peeing a 10 foot stream. Make sure the IR does BOTH sides. Good luck.
