What are the common causes of acute low back pain?

Acute low back pain often arises from various physical causes, and muscle strain, arthritis, and skeletal irregularities are among the most prevalent contributors.

Muscle strain occurs when muscles or ligaments in the back are overstretched or torn, often as a result of improper lifting techniques or sudden awkward movements. This can lead to significant pain and discomfort.

Arthritis, particularly osteoarthritis, can affect the joints in the spine, leading to inflammation, pain, and reduced flexibility. This kind of joint degeneration can lead to acute episodes of back pain, especially if additional strain is placed on an already weakened area.

Skeletal irregularities, such as scoliosis or other deformities, can place uneven stress on the vertebral structures and muscles, leading to acute pain during movements that exacerbate these imbalances.

While other causes such as chronic stress, emotional issues, osteoporosis, aging, and injuries unrelated to physical activity may contribute to back pain more generally, they are not as frequently associated with acute onset as the physical factors mentioned in the correct answer. Understanding these common causes can help in effectively treating and managing acute low back pain.
