Have you done EMG or skin biopsy that confirms peripheral neuropathy ?



Small fiber neuropathy (SFN) is a type of peripheral neuropathy that can be diagnosed by a skin biopsy. SFN can affect the sensory fibers and cause the sensory symptoms in the legs, and it can also affect the fibers of the autonomic nervous system (ANS) which controls the bladder.
I don't know whether the nerves that receive the sensation from the bladder can be affected by SFN.

The autonomic nervous fibers that controls the bladder path from the brain through the spinal cord and exits from the lower part of the spine. So another option might be that any damage along this path can affect the bladder.



Problems in the spine might affect the head. The sympathetic innervation of the head path through the spinal cord, so such problems affect sweating in the head, tears, saliva, constriction of blood vessels, pupils, etc.
Your facial sensory symptoms might be attributed to the trigeminal nerve. I’m not sure, as far as I remember the lower part of the trigeminal nerve is located in the upper cervical spine.
Do you feel these symptoms on one side of the face ? or is it symmetric ?
The trigeminal nerve has 3 branches.
When I had trigeminal neuralgia I felt the pain and other weird sensation only on one side of the face and the exact borders of each of these branches.
