When going through security, always, always make it clear that you have a chronic pain condition, and ask for accommodations. Otherwise you could have the experience I had yesterday. Pat downs are bad enough without someone patting an RSD leg very very firmly. And then sliding the hand down the pants. Sandpaper on a sunburn people, sandpaper on a sunburn. I try not to cry about pain in public, but I did yesterday.
I don't care if it comes across melodramatically, next time, I'm being way more assertive.
