--is just another way of saying that the nerves are damaged, but not dead yet, meaning they overreact and over-fire to what would ordinarily be innocuous stimuli. Allodynia is the term for pain produced from nromally non-painful stimuli, or spontaneously from no stimulus, and parastheses is the term for "weird" sensations produced in the same manner, but not necessarily painful ones (one can think of allodynia as a subset of parastheses).
