Vacations, Suntans, and Flare ups

We all just got back from a 2 week holiday in Florida. Sooo nice to get away and be somewhere warmer and get some sun!! We had 3 kids with us on a 6 hour flight, and they did amazing. Only downside is that we only got a few good beach days, but it was still wonderful. It's been almost a full year since my husband's last major flare up, so going on holidays we made sure we brought the usual things: medication, vitamins. Nothing too much out of the ordinary. About a week into our holiday, we sent a few hours at the beach, and my husband ended up with a wicked burn on his feet. Of all places! Like deep red burn, and don't ever touch him kind of burn. Out of the 7 of us, he got the worst, and it was nowhere else on his body. After some thought, we figured it could be side effect of prednisone which he takes on occasion. Anybody else have that happen? For the rest of our trip he kept his feet covered when we went out, and put layers and layers of aloe vera gel on to soothe the soreness. It's still a bit shocking when you notice signs of a flare up. Even if you've been diagnosed for years or more, they always come at unexpected times. Along with his burn, his ankles started to swell, which for him, is a typical sign of an impending flare up, as he usually gets arthritic flares in his ankles and knees. So when i saw this, I got worried and wondered what would happen next. Last year this time he was hospitalized and treated for sepsis due to severe inflammation from an infection he developed from a Crohn's flare up. That's the short story. Maybe we are more aware now of what signs to watch for, and I think that's a good thing, but I still worry, because I also know that one flare up can be so different than another. How do you handle flare ups or potential ones while you travel? Thankfully we were spending time with family and they were very understanding, but I know that is not always the case.
