I found Rapaflo worked better for me than Flomax, but you're correct that they have similar side effect profiles. The key is to get up slowly anytime you're lying or sitting down so you don't get dizzy. I've also read that your body adjusts to that and after you take it for a while the dizziness is no longer an issue. (But not sure about the other SEs you reported.)
I think going to the ER is pretty rare after HDR brachy, but I did leave the hospital after my first HDR brachy session with a catheter since I couldn't pass the peeing test. (Essentially, you have to show you can pee okay when you're done.) I had zero issues on my second session.
Hope you do well--I essentially had the same treatment as you and after several years I consider myself doing very well.
