Coccydynia

Coccydynia is pain in the area of the coccyx, or tailbone. The coccyx is a small, curved, V-shaped bone at the bottom of the spine.

  • Causes


    This condition is caused by an injury or stress that affects the tailbone, as well as the muscles and nerves surrounding it. Examples include:

    • Fall or trauma
    • Pressure and strain, as during childbirth
    • Spinal cyst or tumor

    • Dislocation from injury or
      obesity
      , which can cause bones to shift
    • Repeated stress (eg, horseback riding, bicycling, motorcycle riding)

  • Diagnosis


    Your doctor will ask about your symptoms and medical history. They will do a physical exam, looking to see if the tailbone area is swollen, red, or warm.

    Imaging studies to look for fractures, dislocation, or other damage in the tailbone may include:

    • CT scan
    • X-ray

  • Prevention


    To help reduce your chance of getting coccydynia, take the following steps:

    • Learn proper sitting posture.
    • If you have to sit for long periods at work, ask for an ergonomics consultation.

  • Risk Factors


    Coccydynia is mor common in female. These factors increase your chance of developing coccydynia:


    • Brittle bones (eg,
      osteoporosis
      ,
      arthritis
      )
    • Low back pain
    • Prolonged sitting on hard surfaces
    • Participation in contact sports or certain activities (eg, horseback riding)

    • Infections (eg,
      tuberculosis
      ,
      osteomyelitis
      )
    • Obesity

    Tell your doctor if you have any of these risk factors.

  • Symptoms

    • All-over backache
    • Pain or spasm of pelvic muscles

    • Limited activity
    • Use of special pillows to sit on
    • Sitz baths (which involves soaking hips and buttocks)
