--is very common with small-fiber syndromes; it is referrred to as allodynia: dysethetic burning/shooting pain from normally non-painful stimuli, such as clothing, due to nerves that through damage have become hypersensitized.

This can also happen in Central Pain Syndrome conditions. in which the spinothalamic sensory relays are damaged, as often happens in MS or stroke (or, truly, any condition that involves damage to that area).

During the most acute phase of my sudden-onset body-wide small-fiber syndrome, I could not tolerate clothing of any type on my body, never mind sheets or even breezes. And, I had spontaneous burning pain even without anything touching me. I am fortunate that gabapentin was effective enough in my case to knock down some of the sensation so I could put on some clothing again, though I still disdain rough fabrics and socks are difficult to tolerate.
