Make sure you bring headphones and an iPod with tranquil music, as well. Books on tape, especially ones on meditation, are useful.

If you use Lidoderm patches, have 4 or 5 out of the wrappers, ready to go. I cut notches in mine to make them adhere better, and use light medical tape as needed. A high quality neck pillow might be worthwhile as well. Bring your own wrap or light blanket--both for hygiene and comfort, don't use the airlines.

If you have a side that is more sensitive, make sure you get a window seat on that side, to minimize contact.

Check with your doc for additional prescriptions and ideas. A sleeping pill might be a good idea--just not Ambien, under ANY circumstances.

Pack healthy snacks. Depending on the airline, they might feed you very well, but it's better to be safe than sorry.

Make sure you pack a few days ahead of time, since it can be a project and elevate your pain.

If your final destination is going to require more ground travel, stay near the airport for a day to rest. I can't stress how much this has helped me. I've learned the hard way that recovery time from a flight (and getting to and from the airport, can take me 4 or 5 days, with travel time in the 5-6 hour range.)

Hope this helps... Some of it might be redundant and/or obvious.
