--paradoxically, one can say "everything is normal".

When it comes to disrupted sensory nerves, one can all manner of weird sensations that don't correspond to any stimulus. Shooting, stabbing, tingling, lancating, electrical, feelings of liquid flowing, feelings of insects creeping, feelings of plastic coating skin, weird sensations of "sponginess", radiating numbness, plain old numbness--and I'm sure I'm forgetting some descriptions that have been used here and other places . . .

Depending on what nerves are involved and how the brain is interpreting erroneous signals, one can get spontaneous sensations of just about anything it is possible to "feel" from actual stimuli. Interestingly, there's not much correlation between the sensation and the degree of nerve impingment or damage--it's a very individual situation.
