Necrotizing soft tissue infection: when to get help

Go through these in order and stop at the first one that applies. If you are reading this for someone else, answer for them.

  1. 1

    Is any of this happening now?

    Call 911

    Go to an emergency department now or call emergency services for severe or rapidly worsening pain, swelling, or skin changes, especially when the pain seems much worse than the visible injury.

    Other emergency warning signs include:

    • Redness or swelling spreading over hours
    • Purple, grey, or black skin
    • Blisters, skin numbness, or blood-stained fluid
    • Fever with confusion, faintness, fast breathing, or extreme weakness
    • Severe illness after surgery, childbirth, an injection, or a wound
    Other emergency signs, for anyone
    • Someone who is struggling to breathe, gasping, choking, or cannot get words out
    • Someone who has chest pain, tightness or pressure lasting more than a few minutes
    • Someone who has sudden weakness or drooping on one side of the face or body, slurred speech, or sudden confusion
    • Someone who is unconscious, or cannot be woken
    • Someone who is bleeding heavily and it will not stop with firm pressure
    • Someone who has had a seizure that will not stop, or does not wake up afterwards
    • Someone who has lips or skin that look pale, blue, grey or blotchy
    • Someone who you believe has taken an overdose or swallowed something poisonous
  2. 2

    Is any of this happening?

    Be seen today

    Do not wait for all symptoms to appear.

    Do not drive yourself if you feel faint, confused, or severely unwell.

    After hospital treatment, contact the follow-up team promptly if a wound becomes more painful, starts draining new fluid, develops spreading redness, or opens.

    And for anyone, someone who:

    • has a fever with a stiff neck, a rash that does not fade under pressure, or severe headache
    • has a wound that is hot, spreading red, or leaking pus
  3. 3

    Does any of this apply?

    Book an appointment

    Routine concerns about scar care, rehabilitation, sleep, or returning to work can usually be discussed at scheduled follow-up appointments unless symptoms are worsening quickly.

Every sign above is quoted from the sofidex article on Necrotizing soft tissue infection. If you are not sure, err upward — it is always reasonable to be checked.
