One more thing I'd like to add that I've recently learned about Lyme and large fiber nerve damage (which I have as well). The immune system mistakes your myelin sheath for the tail of the flagella of the Lyme bacteria. Antibodies are created that damage the myelin of the peripheral nerve and abnormal EMGs start to turn up.

Before my full body condition came on, an EMG found an axonal delay in my right peroneal nerve. The best and brightest could not figure out why. It made no sense because I did not have an injury nor was I doing any of the typical things that cause a compression. Then my full body condition came on like a hurricane a few months later.
