What It Is

Acute back pain is common, and usually not serious. It usually improves within a few weeks (NHS, 2026). It is not always obvious what causes it. A common cause is a pulled muscle (strain), and muscle spasm, the small facet joints of the spine and the discs can all be sources of pain.

So what exactly happens? Well, there are a few processes going on that need to be discussed.

Firstly, acute back pain can occur when bending forwards, bending backwards, or coming up from a forward bend. For example, imagine you are picking up a pen from the floor, you bend forwards, and then something "goes" in your back. Your back is in spasm and you are feeling very sharp pain. This is acute back pain. The pain can be so severe you cannot sit comfortably, or stand for long periods. Lying down may feel the most comfortable at first, but try not to stay in bed for long periods; staying as active as you can and carrying on with your daily activities helps you recover (NHS, 2026).

But why does it occur? Often there is no single clear cause, and back pain often gets better on its own (NHS, 2026).

Lower Back Anatomy

Facet joints are nestled in the back on either side of your spinal column, behind the vertebral bodies and the discs. Each vertebra has a bony prominence on either side, forming a facet joint with the vertebra above and below.

Facet joints are surrounded by a joint capsule, and small folds of tissue similar to a mini version of the knee joint's meniscus have been found within the facet joints of the lower back (Bogduk and Engel, 1984). The facet joints help to limit excessive movement, carry some of the load through the spine and give the spine stability (Perolat et al., 2018).

In-between the vertebrae sit discs, which help the spine absorb force and allow movement. If a disc loses height, more load passes through the facet joints, which may contribute to wear in those joints over time (Inoue et al., 2020).

Surrounding the vertebrae are muscles, ligaments and nerves, all of which can be a source of pain.
