My effected area is my right arm, so I always get a right window seat to avoid being touched, (ask for it and explain why you need this.) I upgrade to First when available--Airtrans is the least expensive airline to do this with. I preboard with the disabled. I rarely get flack for this, but it happens on occasion. I pack warm, soft layers and socks in my carry on bag. I wear Lidocaine patches (once they pulled me out of line to test the patch) and bring extras already cut and ready to go. I start a steroid pack a few days before flying (it helps me cut recovery time from flying down to a few days, as opposed to 5 or so...) Headphones. My nook to read. Meds. I wait till everybody exits the plane, and then I leave.
