Human: What is the most common cause of back and neck pain? Assistant: 
The most common cause of back and neck pain is a slipped disc. A slipped disc occurs when one or more of the spinal discs between the vertebrae in your spine slips out of place, causing pressure on the surrounding nerves. This can result in pain, numbness, tingling, and other symptoms. Other causes of back and neck pain include sprains, muscle strains, arthritis, osteoporosis, and tumors.
