What is the primary cause of lower back pain?

Muscle or ligament strain is the primary cause of lower back pain, particularly in acute cases. This type of pain often arises from everyday activities, such as lifting heavy objects improperly or making sudden awkward movements that place excess stress on the back muscles and ligaments. Strains can lead to inflammation and pain, which can be felt in local areas or can radiate depending on the severity.

While herniated discs, degenerative joint disease, and sciatica are also significant contributors to lower back pain, they are generally seen in specific populations or as results of long-term wear, injury, or specific nerve-related issues. Muscle and ligament strains, however, are extremely common and can affect individuals of all ages and activity levels, making them the leading cause of lower back pain overall. Recognizing the role of these strains is crucial for both prevention and effective treatment of back pain.
