- Trauma to the spine
- Increase in cerebrospinal fluid pressure
- Blockage of cerebrospinal fluid
- Bladder or bowel dysfunction
- Sexual dysfunction
- Nerve pain
- Pain in the lower back, buttocks, legs and feet, vagina, rectum, or abdomen
- Pain when coughing or sneezing
- Weakness, cramping, or numbness in the buttocks, legs, and feet
- Swelling, soreness, or tenderness around the lower end of the spine (sacral area)
- Abnormal sensations in the legs and feet, or less commonly in the arms and hands
- Sciatica symptoms, such as pain when sitting or standing
- The feeling of “sitting on a rock”
- Pulling and burning feeling in the tailbone
- Loss of sensation on the skin
- Loss of reflexes
- MRI scan —a test that uses magnetic waves to make pictures of structures inside the body
- CT scan —a type of x-ray that uses a computer to make pictures of structures inside the body
- Myelogram —an imaging test that uses a special dye to view the spinal cord
- Aspiration of the cyst—a needle is used to remove fluid from the cyst
- Intramuscular corticosteroid injections or other medication injections —to relieve pain
- Prescription medications —such as pain medications, antiseizure medications or antidepressants (both of these may be used to treat pain)
- Lidoderm patches —applied to area of the spine where the cyst is located to provide temporary relief of pain and discomfort
- Transcutaneous electrical nerve stimulation (TENS) —electrical impulses are delivered through the skin to help control pain
- Nonsteroidal anti-inflammatory drugs (NSAIDs) —to relieve pain and inflammation
- Aspiration of the cyst plus fibrin glue injection —a needle is used to drain the cyst and then a special glue is injected into the cyst to try to prevent it from filling again
- Surgery —done if symptoms are severe; nerve damage is worsening; bowel and bladder dysfunction are worsening; or if there is wearing down of the sacrum or other spinal bones
