What are pilonidal cyst symptoms and signs?
If a pilonidal cyst is not infected, there may be no symptoms. When a cyst is infected, signs and symptoms include
- pain to the top of the buttocks,
- low back pain,
- discharge of blood or pus (if abscess ruptures or "pops"), and
- foul-smelling odor.
How do doctors diagnose a pilonidal cyst?
A doctor will diagnose a pilonidal cyst by first doing a physical examination. A pilonidal cyst looks like a lump, swelling, or abscess at the cleft of the buttock with tenderness, and possibly a draining or bleeding area (sinus). The location of the cyst at the top of the buttocks makes it characteristic for a pilonidal cyst.
If infection is severe, blood tests may be performed for diagnosis. There is usually no need for imaging tests in cases of pilonidal cysts.
