Is any of this happening now?
Call 911
Call emergency services for difficulty breathing, fainting, confusion, or swelling of the lips, tongue, or throat.
These can be signs of a severe allergic reaction or another emergency rather than guttate psoriasis itself.
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
Seek urgent medical advice if your skin becomes rapidly and extensively red, painful, hot, or tender, especially with fever, chills, weakness, or pus-filled spots.
These symptoms are not typical of uncomplicated guttate psoriasis.
And for anyone, someone who:
has abdominal pain that is severe, constant, or getting worse

Does any of this apply?
Book an appointment
Arrange a routine appointment if you develop a new, widespread scaly rash, particularly after a sore throat or fever.
An assessment can distinguish guttate psoriasis from infections and other skin conditions.
You should also arrange follow-up if:
The rash is not improving or continues to spread
Itching interferes with sleep or daily activities
You have repeated outbreaks
Treatment is irritating your skin or is difficult to use
You develop persistent joint pain, swelling, or morning stiffness
The condition is affecting your mood or confidence
Every sign above is quoted from the sofidex article on Guttate psoriasis. If you are not sure, err upward — it is always reasonable to be checked.
