You have been to many specialists but I will need to know what examinations were completed. For example, did any of your neurologists order an EEG and EMG to confirm/exclude seizures (epilepsy) or nerve damage to the leg? Did your orthopedists take an X-ray image of your feet and vertebral column? You can try to ask a neurologist, orthopedist, and possibly a psychiatrist to be in the same place simultaneously to examine you together.
