What's the most common cause of back pain?
assistant
The most common cause of back pain is a herniated disc. A herniated disc occurs when one of the soft discs in the spine slips out of place and puts pressure on the spinal nerves. This can cause pain, numbness, or tingling in the lower back, buttocks, and legs. Other causes of back pain include sprains, muscle strains, osteoarthritis, osteoporosis, and arthritis.
