Non-specific low back pain
This is the most common type of back pain. About 19 in 20 cases of acute (sudden onset) low back pain are classed as non-specific. This is the type of back pain that most people will have at some point in their life. It is called non-specific because it is usually not clear what is actually causing the pain. In other words, there is no specific problem or disease that can be identified as to the cause of the pain. The severity of the pain can vary from mild to severe. This type of back pain is discussed further below.

Nerve root pain - often called sciatica
This occurs in less than 1 in 20 cases of acute low back pain. Nerve root pain means that a nerve coming out from the spinal cord (the root of the nerve) is irritated or pressed on. (Many people call this a trapped nerve.) You feel pain along the course of the nerve. Therefore, you typically feel pain down a leg, sometimes as far as to the calf or foot. The pain in the leg or foot is often worse than the pain in the back. The irritation or pressure on the nerve may also cause pins and needles, numbness or weakness in part of a buttock, leg or foot.

About 9 in 10 cases of nerve root back pain are due to a prolapsed disc - often called a slipped disc. (A disc does not actually slip. What happens is that part of the inner softer part of the disc bulges out (prolapses) through a weakness in the outer harder part of the disc. The prolapsed part of the disc can press on a nerve nearby. See separate leaflet called 'Prolapsed Disc (Slipped Disc)' for details.) Other less common conditions can cause pressure on a nerve to cause nerve root pain.

Cauda equina syndrome - rare, but an emergency
Cauda equina syndrome is a particularly serious type of nerve root problem. This is a rare disorder where the nerves at the very bottom of the spinal cord are pressed on. This syndrome can cause low back pain plus: problems with bowel and bladder function (usually unable to pass urine), numbness in the saddle area (around the anus), and weakness in one or both legs. This syndrome needs urgent treatment to preserve the nerves to the bladder and bowel from becoming permanently damaged. See a doctor immediately if you suspect cauda equina syndrome.

Less common causes of low back pain
Arthritis (inflammation of the joints) of the spine sometimes causes back pain. Osteoarthritis is the common form or arthritis and usually occurs in older people. Ankylosing spondylitis is another form of arthritis that can occur in young adults and causes pain and stiffness in the lower back. Rheumatoid arthritis may affect the spine, but you are likely to have other joints affected too. There are separate leaflets on each of these types of arthritis.

Various uncommon bone disorders, tumours, infections, and pressure from structures near to the spine occasionally cause low back pain. (Less than 1 in 100 cases of low back pain.)

The rest of this leaflet is mainly about non-specific low back pain - the common type of low back pain.
