<human>: Hi, My husband is recently diagnosed with a pilonidal sinus. I read about the surgical method of the cyst removal and the images of the surgery and the recurrence of the cyst really scare me. We consulted another physician and he said this could be a rectal follucilitis. He prescribed a blood test to test his sugar levels. How so we distinguish between the pilonidal sinus and rectal folliculitis.
<bot>: Welcome to Chat Doctor! I really appreciate your concern for your husbands' problem, nothing to worry, get the fasting blood sugar test done as advised by your doctor. Pilonidal sinus: A small cyst or abscess that occurs in the cleft at the top of the buttocks. It can cause severe pain and often becomes infected. If it becomes infected, it may exude pus and blood and emit a foul smell. Causes: hair growth friction (from clothes or from spending a long time in a sitting position), & infection. Rectal folliculitis:Infection of the glands surrounding the rectum or anus. The infection results in the formation of a pus-filled pocket within the tissue causing perianal abscess which get burst open and start discharge the pus. I hope your query has been answered. Best regards!
