--it is possible that the hypothyroidism is contributing to your neuropathy.

Hypothyroid neuropathy is not that well known to most general practitioners (or even to a a lot of endocrinologists), but it is certainly documented, and often shows up in the hands/wrist/arms (it can present very much like carpal tunnel), in that low thyroid hormone status leads to mucin deposits in the tissues, which restricts room through which nerves but pass and often results in nerve compression--and this tends to happen more often in those places in which the nerves have to go through narrow spaces to begin with, like the wrist, elbow, and ankle. (Mrs. D has posted about this on these boards fairly often.)

Interestingly enough, many of the articles that delve into this most deeply come from France.
