Take pictures of your flares, and document all your symptoms. I have kept a photo-log since the beginning. It has been invaluable when discussing, or proving, what you are referring to.
Alternatively, I have made it a point to drive myself 50 miles to the closest walk-in clinic while the flares are happening. As soon as the attending physician enters the room, pull off your socks and show them. There seems to be a hesitancy these days towards “hands on” . But if they won’t look....then you have to show.

I suffered for years because every doctor I went to about my symptoms couldn't "see" the flareups. Taking photos helps. I can't wear socks or close-toed shoes, even in winter unless it's freezing and there's snow on the ground! Sometimes I'd like to just walk in the snow!
