--but nerve swelling, and excessive branching, are not generally "normal" findings.

It sounds like yours are patchy and not widespread, though. This may mean that the "snapshot" that this skin biopsy has caught is of a neuropathic process at an early stage (so it is a good idea to get another skin biopsy after some period of time). Let's hope that perhaps whatever process is going on does not progress, or can be halted--there are some toxic (often chemotherapeutic) exposure/post-viral neuropathic situations that may show "subclinical" neural damage that may, given the right conditions, heal over time.

How are your symptoms doing? (Often, there isn't much of a corrrelation between objective signs of nerve damage and the severity of symptoms--in fact, severely damaged nerves that have "died" often result in fewer symptoms, mostly numb patches, than nerves being actively damaged, or those that are experiencing repair--the latter tend to be painful.)
