Their can be several causes of itchy skin at the base of the tailbone or the crease of skin between the buttocks. Some of these may require medical treatment. The physicians best qualified to discuss this issue include your primary care doctor
, your family medicine doctor
, or your dermatologist
The most common cause of itchy skin at the base of the tailbone or between the buttocks is a simple irritation of the skin or an allergic reaction. Often simply attention to good hygiene and keeping the skin dry is enough to clear the condition up. At times, your physician may recommend a barrier cream, such as a vaseline-containing product, to protect the skin. Occasionally, a new laundry detergent or personal care product is the culprit, and your physician can assist you with identifying the offending agent.
Occasionally, a skin infection, particularly a fungal infection, may be the culprit. If this is the case, your physician may prescribe a antifungal cream.
Rarely, a bacterial skin infection or an abscess at the base of the tailbone, called a pilonidal cyst, may be the culprit. In these cases, antibiotics or drainage of the infection may be indicated.
As always, the diagnosis or management of your specific condition will require a physical examination by your personal physician. Scheduling an office visit with your primary care doctor or dermatologist is recommended.
