Shy of hanging a big sign around your neck that says "CONTAGIOUS", I don't have any great ideas.

I am lucky to not be as super sensitive to touch as most RSD'ers are. My issues are mostly to the left of my neck over towards my shoulder and the left front of my neck to my collarbone. I'm okay with the perfect bra and tank tops most of the time and those aren't areas that strangers normally touch.

I do have issues when socializing with friends. My family does the peck on the cheek for greetings and saying goodbye. My friends are more huggers. Parrothead friends who have enjoyed too many cocktails and HANG on me when hugging is the worst !

If I see the hug coming, sometimes I can dodge it and say, "Oops, no hugging today, bad neck day" but often I'm trapped. It must be so much more difficult for you....stuck in the wheelchair, you're more of a sitting duck
