Pilonidal Disease

These hairs then continue to grow and burrow deeper into the fat layer below the skin. Eventually, a track or sinus develops where the hair has grown deeper. It is frequent to have more than one sinus. Symptoms of the disease may include some pain at the base of the spine, swelling in this area, discomfort on sitting down and discharge of infected or bloody contents. Occasionally, a painful abscess can occur accompanied by the feeling of being generally unwell, fever and marked increase in pain. If left untreated, the symptoms normally wax and wane but do not usually disappear by themselves. The only effective way of treating this is by surgery.
