I was told my PN was idiopathic. The neuro I saw didn't go past the basic tests to rule out auto-immune disorders or diabetes. So I don't really know where it came from or why.

With the carpal tunnel surgery I know people that have had the surgery twice. So I suppose it could be done for the TTS as well. It's not a one time thing in other words. If you have it once it doesn't mean it can't be done again.

I'd like to know more too. Because at this point I feel like we're throwing meds at just the symptoms without identifying or treating what might be an underlying cause. And there is a time factor to carpal tunnel syndrome I know...don't know if it applies to TTS too, that is if the condition goes untreated for long enough permanent nerve damage can occur and then the surgery is of limited value. Though with what I'm learning here there really may be no such thing as permanent nerve damage.
