Back Pain

Back pain affects most people at some point in life, ranging from a dull, nagging ache to sharp pain that limits movement.

Common Causes

Most back pain stems from mechanical issues — strained muscles or ligaments from lifting, poor posture, or sudden awkward movement — rather than a serious underlying disease. Our lower back pain causes guide covers the specific causes of the most common location in more depth, including disc problems and sciatica, a distinct condition involving nerve pain radiating down the leg.

What Helps Most Cases

Staying gently active, rather than prolonged bed rest, generally speeds recovery. Over-the-counter pain relievers, heat or ice, and gentle stretching also help — our lower back pain treatment guide covers this in depth.

When It's More Than a Strain

Most back pain improves within a few weeks. Pain that's severe, doesn't improve, or comes with numbness, weakness, or bladder/bowel changes suggests something beyond a simple strain and needs evaluation.

Red Flags That Need Prompt Attention

Seek medical care promptly for back pain following a significant injury, with fever, unexplained weight loss, numbness in the groin area, or new bladder or bowel control problems — these can signal a more serious underlying cause. The same is true for new or worsening leg weakness or numbness, a personal history of cancer, and even a minor fall or bump in someone with osteoporosis or long-term steroid use — these can point to nerve compression, cancer that has spread to the spine, or a fragility fracture, respectively.
