Low Back & Pelvis

What It Is

Almost every adult will experience pain in their lower back at one point or another. The pain can range from mild to severe. It can be short-lived or long-lasting. Regardless of how it happens, lower back pain can make it difficult to do your regular daily activities (American Academy of Orthopaedic Surgeons, n.d.a).

Around 60 to 80% of people have lower back pain at some point in their life (American Academy of Orthopaedic Surgeons, n.d.b). It's very common, and can be very debilitating. Lower back pain can be acute (recent and short-lived) or chronic (long-lasting), specific or vague, and achy, and it can spread into the legs as pain, aching or pins and needles.

Back pain can affect your day-to-day living by limiting sport, housework, hobbies or work.

Back pain usually improves within a few weeks, but it can sometimes last longer or keep coming back (NHS, 2026). There are many treatments, which are discussed later in this sheet.

Low Back Pain Anatomy

Understanding your spine and the way it works will help you understand what is causing the pain in your lower back. Your spine is made up of many small bones (vertebrae), stacked one on top of the other. Ligaments, muscles, intervertebral discs and nerves are the other parts of your spine.

The vertebrae connect to form a canal that protects the spinal cord. The spinal column has three sections creating three curves in the back: the neck (cervical), the chest area (thoracic) and the lower back (lumbar). The lowest part of the spine (the sacrum and coccyx) is made up of vertebrae that are fused together.

The nerves and spinal cord act like electrical cables. They travel through the canal and carry messages between the muscles and the brain. Nerves branch out from the cord through openings between the vertebrae. The most famous of these is the sciatic nerve, which causes sciatica when it is trapped or pinched. Sciatica pain tends to travel into the buttock, down the back of the leg and sometimes into the foot and toes, and it can cause tingling, numbness and weakness in the leg (NHS, 2024). The other main nerve that comes from the lower back is the femoral nerve, which tends to cause pain down the front of the thigh to the knee.

The ligaments and muscles provide the stability and support your spine and upper body need. Strong ligaments connect the vertebrae to one another.
