--can have a whole host of abnormal sensations: burning, stinging, aching, electrical jolts, feelings of something touching the skin when there's nothing there, weird feelings of heat and cold without obvious sources, numbness . . .it all depends on the extent and kind of damage to the nerves and how the brain is interpreting the abnormal nerve firing.

It is also true that nerves that are healing, in the sense that nerve growth cones are fighting through other tissue and trying to hook back up to their efferents, may well produce all sorts of unusual sensations that can be hard to distinguish from nerves that are continuing to undergo a damage process. In such cases, often these parastheses recede slowly over months as the brain gets used to the new firing patterns. It's why those of us who are prone to "flares" or wide variations in symptoms like to keep diaries of our symptoms--it's often hard to notice the long-term pattern except in retrospect.
