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
  • Prolonged sitting on hard surfaces
  • Spinal cyst or tumor
  • Dislocation from injury or obesity, which can cause bones to shift
  • Repeated stress (eg, horseback riding, bicycling, motorcycle riding)

عوامل الخطر

These factors increase your chance of developing coccydynia:

  • الجنس: أنثى
  • Brittle bones (eg, osteoporosis, arthritis)
  • Low back pain
  • Participation in contact sports or certain activities (eg, horseback riding)
  • Infections (eg, tuberculosis, osteomyelitis)

    • Having sex
  • Tenderness directly over tailbone

التشخيص

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

  • التصوير المقطعي المحوسب - نوع من الأشعة السينية يستخدم جهاز كمبيوتر لعمل صور لهياكل داخل الجسم
  • X-ray —a test that uses radiation to take a picture of structures inside the body, especially bones

These tests can show if there is a fracture or dislocation.
