What causes pain at the tip of the coccyx in the middle of the buttocks?

If symptoms occur at the tip of the coccyx in the middle of the buttocks, they may be caused by a herniated disc. A herniated disc can cause the inner portion of the spinal disc to bulge, compressing the nearby nerve roots and resulting in pain.

In addition to a herniated disc, such symptoms could also be due to conditions such as osteoarthritis, discitis, lumbar disc herniation, lumbar spinal stenosis, lumbar fractures, or neuropathy.
