A boil is a red, swollen, painful bump under the skin. It often looks like an overgrown pimple. Boils are often caused by infected hair follicles. Bacteria from the infection form an abscess, or pocket of pus. A boil can become large and cause severe pain. Boils most often happen where there is hair and rubbing. The face, neck, armpits, breasts, groin, and buttocks are common sites.
An epidural abscess is a localized collection of pus between the dura mater and the skull or vertebral column. A spinal epidural abscess is a pocket or collection of pus that develops in or near the epidural space in the spinal column. The epidural space is located in a critical spot on the human body between the vertebrae and spinal cord. What causes a spinal epidural abscess? The cause can be from a remote source such as distant infection or something closer to the epidural space. There are many spinal epidural abscesses without an identifiable source.
