So sorry your having pain again. But it sounds like you pushed yourself even though you were feeling good. I get that way too. I try hard not to over due stuff when I'm feeling good because I know I can put myself into painland, especially my hip.
I've tried the motorized carts at target when shopping, glad I did at the time. Vegas can be a lot of walking if you haven't been there b/4 and want to see lots of sites. A scooter or a wheelchair would be great idea, though!
Have a relaxing evening,
