Check in the 'stickies' section. LizaJane has all the tests usually done to find neuropathy and the causes of neuropathy. It is a shame your neuro upset you with a premature diagnosis. It appears that you have a lot more testing to undergo before any nerve damage can be ruled in or out, let along a cause like leprosy.

Usually an epidermal nerve fiber biopsy (simple procedure) is the test to rule out axonal damage, and without it, axonal damage can not really be ruled out.

HNPP can be genetically tested for, and about 30 Charcot Marie Tooth (hereditary neuropathies) have been identified. No need for him to leave you guessing on those either. Prior to doing genetic testing, you need to know what kind of neuropathy you have. There are literally hundreds of reasons for neuropathy, and hereditary is usually considered when you get put in the 'idiopathic' group, of which 42% eventually is deemed to be hereditary. Not all hereditary has an identified gene locus, so, sometimes, you will be told you have a hereditary PN without locus if other data leans in that direction.

Leprosy is such a longshot, I would not lose any sleep over it. As was mentioned in the other post, CIDP, a nutritional deficiency, diabetes, celiac disease, autoimmune diseases, (many), sarcoidosis, amyloidosis and then hereditary come to mind, way, way before leprosy!

Yes, by all means, get your records, and find a research center, that does skin biopsies, and also specializes in PN.
