Warning-sign checks

Langerhans cell histiocytosis: 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

    Call emergency services for severe breathing difficulty, collapse, a seizure, marked confusion, or sudden weakness affecting the face, arm, or leg.

    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

    Drinking and urinating much more than usual also needs prompt assessment, particularly in someone with current or previous LCH.

    Seek urgent medical care for:

    • Sudden chest pain or new shortness of breath
    • Repeated vomiting with excessive thirst and urination
    • New weakness, loss of balance, confusion, or severe headache
    • Rapidly increasing abdominal swelling
    • Unusual bleeding, widespread bruising, or signs of serious infection
  3. 3

    Does any of this apply?

    Book an appointment

    Arrange a routine medical appointment for persistent bone pain or swelling, an unexplained rash, repeated ear discharge, loose teeth without a clear dental cause, or ongoing cough and breathlessness.

    If you have been treated for LCH, report new symptoms rather than waiting for the next scheduled follow-up.

    This includes changes in growth, puberty, balance, coordination, hearing, vision, thirst, urination, or breathing.

Every sign above is quoted from the sofidex article on Langerhans cell histiocytosis. If you are not sure, err upward — it is always reasonable to be checked.
