Are you under the care of a neuro? If not I would find one in your area or maybe your orthopedic can refer you to one. I know since my issue though a little different then what you are stating is in my legs that did mris of my brain and spine. Have you had that done and what about emg? Have you had a complete bloodwork done checking for deficiencies and auto immune? May I ask if you have any other health conditions,age,when this started? Hang in there and trust me I have seen that blank face many of times from doctors. Frustrating and scary but really this forum has really helped me face my fears and feelings
