Flying is an issue for many of us. There are other threads that discuss various coping mechanisms to deal with flying. I flew in 3 (if my memory serves me right) days early before I went on a cruise to try and get back to my baseline pain level.

I had no issues with the movement of the ship and I'm incredibly hypersensitive. I bring a down pillow to cradle my dominant arm when being driven any distance or when I fly. Ships can widely vary in size though, and the newer ones have better stability, so you might want to research your specific ship.

The best part of the trip was being able to swim in warm ocean water--I'm pretty much pain free there. I had a massage on board and utilized the ship's sauna and pool as well.

Regarding breezes, I wore Lidocaine patches over my most sensitive area and there are areas on the deck that are fairly well protected from breezes much of the time.

I did as much as I could tolerate and spent as much time in bed or relaxing and reading as I felt I needed. It was worth it to me at the time, but I think the person I was travelling with would have preferred a more active travel mate.
