--is very common with small-fiber syndromes, although other sensations can be there simultaneously.

This usually means, at the least, that the nerves involved are damaged, but not dead--that would involve numbness. People sometimes report both these dysesthetic sensations and numbness in the same area, as individual fibers are at differenent stages of damage.

The hope is that if a cause of neuropathy can be found and treated, or, in idiopathic cases, the initial damaging process relents, and the deterioration arrested, that the small fibers will eventually start to regenerate, and the dysesthetic feelings will lessen over time. But it may be a LONG time (years).
