Barbara, Sensory neuropathy is a disorder where the nerves of sensation are affected, as opposed to the nerves that control muscle movement. My guess is you have a sensory neuropathy.

It's time for you to collect your data. Ask your doctors to send you copies of all the lab tests they've done. Have you had nerve conduction studies? Get copies of those, too. Look at the list of tests on lizajane.org, or, if you are really ready to get into doing research on your own, any other site.

But do make sure your doctors investigate and look for a cause, before saying what you have is "idiopathic". How old are you now? Because the younger you are, the more important it is to look thoroughly.

Good luck with this.
