My experience with this condition started with me waking up with my leg numb and when I tried to use it, it wouldn't work. I lost my balance and fell. Called my GP who stated that it was a neurological problem and sent me to a neurologist. My EMG/NCV showed PN, numbness, and lumbar radiculopathy. I'm still waiting to see a neurologist as the first one I saw just ignored it. I'm sorry I can't share anymore information with you. I know how tiring it is to be shuffled from doctor to doctor, but you need to find a neurologist who is willing to try to help you. Good luck and take care.
