Thank you for choosing health care magic. I can understand your concern. Usually in such cases neurophysicians or neurosurgeons will wait for some time for symptom resolvement before they take any call for surgery. Sometimes even after surgery results may not be promising. I advise you to see a neurophysician along with reports. Based upon the physical examination he can advise you whether your father is the best candidate for medical treatment or surgical treatment
. I wish him a speedy recovery.
