A further thought on the EMG testing you mention. Yes, it is good to help confirm damage to the nerve - but it cannot be used to rule out TTS. I've read this and been told this on a number of ocassions by different doctors. Also, according to a doctor on the neuropathy bulletin board, there is no way to know for sure what is causing damage to the nerve - only that it's happened. For example, the testing may show problems with the lateral nerve but the problem could be from TTS or it could be from damage from diabetes. Apparently (according to him anyway) there is no way to tell the difference (as in what's _causing_ the problem. This was news to me, I thought you may find it interesting.
