Why Does Degenerative Disc Disease Cause Lower Back Pain?

Spinal discs sit between the bones of the lower back and help distribute pressure during movement. With disc degeneration, the disc can lose some of its normal flexibility and height. The outer part may become sensitive, while nearby joints and muscles take on different loads. These changes can cause aching, stiffness, or pain that varies with sitting, bending, lifting, or prolonged positions. Some people have disc changes without pain, and lower back pain can have several causes, so symptoms and a physical examination matter more than an image alone.

Keep gently active within tolerable limits rather than staying in bed for long periods. Change position regularly, use lifting technique that keeps the load close, and build back and hip strength gradually with professional guidance. Heat or cold may be useful according to your preference. A clinician can tailor exercises and discuss pain relief safely, especially if you have other medical conditions or take regular medicines.

Arrange medical advice if pain is persistent, worsening, or limiting walking, work, or sleep. Seek urgent care for new loss of bladder or bowel control, numbness around the inner thighs or genitals, rapidly worsening leg weakness, or severe pain after major trauma. Fever or feeling very unwell alongside back pain also needs prompt assessment.

What features suggest disc-related pain in my case? Do I need imaging, or would an examination guide treatment? Which activities and exercises should I start with, and what symptoms require an urgent review?
