I have an abscess in my upper anal region. it is just below my coccyx ?

May be pilonidal: A pilonidal sinus is a small hole, that may lead to a tiny tunnel, in the skin. It is usually at the cleft of the buttocks where they separate at the top. Showering each day helps keep the area clean, but there is nothing else to do for it unless the pilonidal sinus becomes infected. Then, it is treated with antibiotics and sometimes needs surgery to remove a cyst that has formed under the hole.
