I have had several nerve conduction and muscle testing done. On my legs for lumbar surgery, on my arms and hands and neck to assess numbness in my hands and elbow compression. The report is a long list of reaction times that show where the compression or block is. They do the ablation by ultrasound or x-ray guidance. I was referred to a pain management clinic by a neurosurgeon where a doctor told me about options. The neurosurgeon did not want to do any surgery unless it got worse. I had already had 3 back surgeries over 30+ years.
