Coccydynia (tailbone pain)
Coccydynia is a pain felt in your coccyx (tailbone). This is the last bone at the bottom of the spine (tailbone). You can get it if you injure or strain your coccyx or the surrounding muscles and ligaments.
In most cases, the pain will improve over a few weeks or months, but occasionally it can last much longer and severely affect your ability to carry out everyday activities.
The main symptom is pain and tenderness in the area just above the buttocks.
The pain may:
- be dull and achy most of the time, with occasional sharp pains
- be worse when sitting down, moving from sitting to standing, standing for long periods, having sex and going for a poo
- make it very difficult to sleep and carry out everyday activities, such as driving or bending over
Some people also have back pain, shooting leg pains (sciatica) and painful buttocks and hips.
Coccydynia will often improve on its own after a few weeks and there are some simple treatments you can try at home.
See your GP if:
- the pain does not start to improve within a few weeks
- simple home treatments do not relieve the pain
- your pain is very severe
- you also have bleeding, a high temperature or pain away from your coccyx
Your GP will carry out an examination to check for more serious causes of your pain, such as infection or a fracture.
Common causes of coccydynia include:
- an injury or accident, such as a fall
- repeated or prolonged strain on the coccyx
- poor posture
- being overweight or underweight
In many cases, no obvious cause can be found. Age-related "wear and tear" may play a part.

There are a number of treatments for coccydynia.
Simple measures you can try at home are usually recommended first and other treatments may be used if these do not help.
The main treatments are:
- self-care measures, such as avoiding prolonged sitting, using a specially-designed coccyx cushion (doughnut cushions), applying hot or cold packs to your lower back and wearing loose clothing
- non-steroidal anti-inflammatory (NSAID) painkillers that you can buy from shops and pharmacies, such as ibuprofen
Persistent symptoms lasting longer than 8 weeks may benefit from:
- physiotherapy exercises, massage and stretching
- injections of anti-inflammatories (corticosteroids) and painkillers into the coccyx or surrounding area
In a small number of cases where other treatments have not helped, surgery may be needed to manipulate the coccyx. Very rarely the coccyx may need to be removed (coccygectomy).
