Overall, I'm glad I went, but there were moments where I was in a lot of pain. Between the flight down and the first evening, which wasn't really all that much walking, my leg swelled up pretty bad the first night and then broke out in a rash from all the swelling. I guess it's partially my fault, normally I would have started the Ibuprofen 800's 3x/day a few days before I left. I wound up having to take a round of steroids and the 800's to bring the swelling down. My leg still didn't look normal but it was a whole lot better after that. I think that I will be discussing this with my DR prior to my next trip in April to try and figure something out to make things easier. I tried to slow down and relax a bit and put my leg up when I could, but that is easier said than done. By the end of the night I was definitely hurting and moving slower, but I tried not to let it stop me. I was traveling with friends and aside from the one I roomed with, I don't think anyone noticed at all, so I guess I did okay.
FWIW, so you can compare, my injuries are all in the knee and hip of my left leg, and I also have a lot of nerve and soft tissue damage. It's been over four years since the accident so it's obviously not going away. Physical therapy made it worse. I was told that I could count on arthritis in my knee and hip by the end of my thirties. My knee no longer has the correct alignment that it should have either.
I don't know that the PP was talking about actual disabilities either, but I guess it just bugs me because as much as I know I have problems, someone looking at me wouldn't know that and would just assume I was another fat, lazy American who didn't want to walk around WDW. I know that it's my issue to get over, but hearing the assumptions confirmed makes it hard for me to admit that I need that help.
I hope that you go and have a fabulous trip. Pain and swelling aside I had a really great time and I'm glad I went. I am just investigating what I should do for our family trip in April to not have problems, or to have less problems. At the very least I will be starting the Ibuprofen 800's a few days before leaving. Good luck!
