NHS Fournier's gangrene symptoms emergency perineal pain fever

Pain between the scrotum and anus (the perineum) with a fever or local warmth needs urgent in-person assessment today, preferably at an emergency department.
It can be caused by an infection such as a perineal/anal abscess or prostate infection. Rarely, a rapidly spreading infection called Fournier gangrene can begin with severe perineal or genital pain, swelling/redness, fever, or feeling unwell, and requires immediate surgery and IV antibiotics. A urology text notes that Fournier gangrene can arise from the perineal skin, scrotum, urethra, or rectum and needs emergency treatment. Campbell-Walsh-Wein Urology
Go to emergency care now if you have any of these:
  • Fever 38°C or higher, chills, weakness, or rapid worsening
  • Redness, swelling, a lump, pus, skin turning dark/purple, blisters, bad smell, or crackling under the skin
  • Pain that is severe or much worse than the visible skin changes
  • Difficulty passing urine, painful urination, blood in urine, rectal pain, or trouble sitting
  • Diabetes, immune suppression, recent surgery/injury, or use of an SGLT2 diabetes medicine such as dapagliflozin, empagliflozin, or canagliflozin
Do not squeeze, cut, or try to drain the area yourself. You may take paracetamol/acetaminophen if you normally can, but do not delay getting examined. NHS patient guidance also treats genital/perineal pain, swelling or redness with fever as an emergency warning pattern for Fournier gangrene. NHS warning guidance

anorectal abscess AND drainage

ASCRS anorectal abscess clinical practice guideline drainage antibiotics 2022

A suspected perineal/perianal abscess needs urgent in-person examination today. With your earlier symptoms of pain between scrotum and anus plus local heat/fever, go to an emergency department now, particularly if pain is severe or worsening.

Usual management by a clinician

  1. Assess for emergency infection
    • Examination of the perineum, scrotum, anus, and rectum.
    • Check temperature, heart rate, blood tests, urine testing, and blood glucose.
    • Urgent surgical/urology assessment if there is spreading redness, severe pain, skin discoloration, crepitus, systemic illness, diabetes, or concern for Fournier gangrene.
  2. Drainage is the main treatment
    • Most true perianal/perineal abscesses require incision and drainage, often under local or general anesthesia depending on depth and location.
    • Antibiotics alone usually do not adequately treat a walled-off collection of pus.
    • Deep abscesses, such as ischiorectal, supralevator, or scrotal/perineal collections, may need ultrasound or CT imaging and drainage in hospital.
  3. Antibiotics are added when indicated
    • Usually if there is fever/sepsis, spreading cellulitis, immune suppression, diabetes, extensive/deep infection, recurrent disease, or certain heart-valve risks.
    • The choice must be prescribed locally and should cover likely bowel and skin organisms when appropriate. The ASCRS guideline recommends reserving antibiotics for abscesses complicated by cellulitis, systemic infection, or immunosuppression.
  4. Aftercare after drainage
    • Warm sitz baths, gentle cleaning, absorbent dressing, stool-softening measures if painful bowel movements, and prescribed pain relief.
    • Follow-up is important because a fistula can develop or the abscess can recur.

Do not do at home

  • Do not squeeze, puncture, or attempt to drain it yourself.
  • Do not delay care while trying antibiotics, creams, or pain medicines alone.
Emergency signs: fever/chills, rapidly increasing swelling/redness, pus or foul smell, dark/purple skin, crackling sensation, inability to pass urine, confusion, or pain out of proportion to what you can see. These can signal a rapidly spreading infection that needs immediate surgical treatment.
