--about why the heat lamp was used before the NCV/EMG, unless it was to warm muscles and make them more pliable for the EMG part of the test, but everything I've ever read about nerve conduction indicates that heat slows transmission. Maybe some neurologists like to see how one's nerves function under more aversive conditions-- a normal study under heat probably means there are no problems in the areas tested.

The MS people are really adamant about cooling helping to ease nerve transmission symptoms; in fact, cooling vests are prominently displayed and sold in most MS publications.

Ohaya, I think they'd still be interested to do an MRI post second surgery--something might have slipped or there might be compression in a new spot. Of course, it's possible the problems stem from farther down the nerve pathways than the spine, so it would be helpful to have the NCV/EMG reports, to see exactly where and what was tested (you should get and keep copies of all test results anyway).
