--could very well be signs of axonal regeneration. Nerves tend to create all kinds of weird sensory signals/symptoms--pain, shoots, tingles, a feeling of "banding" when there's nothing there--when they are attempting to re-synapse, and fighting through other tissues to do so. In time, the brain tends to get used to these signals and to intepret them in a more normal manner.

Of course, these are exactly the same kind of symptoms one gets when nerves are being damaged. That's the problem--it's very hard to tell which way things are going except in long-term retrospect, and by that I mean over months to years. It's often instructive to keep a diary and compare things month to month, or season to season; does one overall have fewer symptoms over long time periods. If the answer is yes, it is likely the nerves are doing at least some slow regeneration.
