Hi, Thanks for writing in. It is possible that your symptoms of severe pain in the hip and knee regions are due to irritation of nerve roots in the lumbar spine. This is known as radiculopathy. It happens due to nerve root irritation due to slight movements including when you are doing active physical movements. This causes pressure on nerves roots and pinching of the nerves. This is followed by sudden shooting pain from the lower back to the hip and can also be experienced behind the knee. Your doctor wants to know the exact details of nerve pinching should it have occurred in your lower back region. This will help guide your treatment. If you feel severe pain then apply a little ointment containing pain reliever and muscle relaxant. Please discuss treatment available for degenerative cervical disc disease with your doctor and if it is a serious concern. Please do not worry.
