What Causes Lower Back Pain?

If you experience lower back pain that affects your daily life, you’re not alone. Nearly 65 million Americans report a recent episode of back pain and over 16 million experience chronic back pain that affects their everyday activities.¹ Lower back pain is also the leading cause of disability worldwide.² While lower back pain doesn’t always indicate a serious problem, understanding the causes and symptoms of your pain can help you find treatment options.

What Is Lower Back Pain?

Back pain is one of the most common reasons people see a doctor and ranges from mild and temporary discomfort to severe, ongoing pain that affects your daily life.³ There are two types of back pain:³

• Acute. Short-term back pain, called acute back pain, resolves within a few days to a few weeks. For most people, lower back pain is acute and resolves on its own. Over-the-counter pain relief can help soothe acute symptoms while you recover.
• Chronic. Lower back pain that persists for longer than 12 weeks is defined as chronic back pain. Even after the initial injury or cause of back pain has been treated, some people experience chronic pain. Of all people affected by acute back pain, 20% will develop chronic back pain. While persistent pain may signal a more serious issue, sometimes there is no underlying cause to identify or treat. Treatment options can help ease symptoms even if they don’t entirely resolve them. If back pain becomes chronic, you should speak with your doctor.
