Is any of this happening now?
Call 911
Call emergency services or go to an emergency department immediately for severe or rapidly worsening pain with swelling, redness, or skin colour change.
This is especially important when the pain seems much worse than the skin looks.
Other emergency signs include:
Rapidly spreading swelling or discolouration
Blisters, black or grey skin, or fluid leaking from a wound
Fever with confusion, faintness, fast breathing, or extreme weakness
New numbness in a previously painful area
A crackling feeling under the skin
Rapid deterioration after surgery, injury, or a wound infection
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

Is any of this happening?
Be seen today
Do not wait for a routine appointment if these symptoms are present.
Do not rely on home antibiotics or pain relief to see whether the problem settles.
After hospital treatment, contact the surgical or wound-care team promptly for increasing wound pain, new drainage, fever, worsening redness, or problems with a graft or dressing.

Stable scars, mobility concerns, persistent tiredness, and ongoing rehabilitation needs can usually be discussed at planned follow-up unless they suddenly worsen.
