Hello, Welcome to health care magic. I am Dr Alok Sinha, MD Psychiatry from India. I have read your question carefully and understood it. I can understand your concern. I will try my best to answer your query. The condition you are mentioning here is called prolapse intervetebral disc with neuronal compromise. I will make you understand this disease. Our vertebral column is a bony structure which is made up of many bones called vertebrum. vertebral column is hollow towards posterior side to accommodate spinal cord. In between two vertebra there is a cartilagenous disc which is a main part of vertebral joint. Sometimes due to wear and tear or injury to vertebra, a intervertebral disc gets prolapsed and bulges posteriorly. If this prolapse is severe then this disc may impinge upon the spinal cord and emerging spinal nerves roots. This condition is dangerous as it may cause paralysis of lower portion of body. In your father s case it is more complicated due to multiple levels of involvement at both cervical (neck) and lumbar region. Sooner or later surgery may be required. I suggest you to follow the advise of his treating neurosurgeon who may advice correctly the right time of surgery according to functional capacity of your father. I wish your father a better health.
