Overview:

The coccyx bone, or tailbone, is located at the base of the spine below the sacrum. The term coccydynia refers to pain that occurs in this area and is usually felt when sitting which puts direct pressure on the coccyx. Women are more likely to have pain in this region. The most common causes of discomfort in the coccyx region are due to dislocation or rigidity of one of the joints, muscles spasms due to falls, childbirth, repetitive strain, or surgery. Being overweight or underweight can also make one more prone to coccydynia. In fact, obesity creates a lot of extra pressure in this area, and in the opposite case, the lack of fat can cause friction between the coccyx and other tissues. Other less common causes of this condition include cysts, infections or in the worst-case cancer.
