nonnasally,
I understand completely! I have had my trip booked since the last one last year in October. DD is a competitive dancer and now has tendonitis in both knees. She has been doing physical therapy for a few months, but this past week, both knees swelled and she has been complaining more about the pain. She goes in tomorrow to see the dr and I expect him to say no dance or PE for at least a month. We leave the next day.
On top of that, I am battling planter fasciitis in my right foot. I also have been in physical therapy and my heel has been getting better until the last week.
I have all of these plans in place and now wonder just how much we will be able to do. I do have insurance, but the thought of canceling is worse than the thought of just doing less.
I would take it day by day. If you DH is up for it, I'd take him. You can also rent a
scooter if that would help him. Be sure to check out the disabilities thread here on the DISboards. There are a lot of people who can offer advice and support.
Hang in there. You are not being selfish. Hopefully, your plans will work out.
