Lambert-eaton myasthenic syndrome: 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

    Seek emergency help for severe or rapidly worsening breathlessness, inability to swallow saliva, repeated choking, a very weak cough, or bluish or grey lips or skin.

    These can indicate serious breathing or swallowing weakness.

    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

    If you already have LEMS, contact your care team promptly for:

    • A clear or lasting decline in strength
    • New choking, coughing during meals, or changes in speech
    • Repeated falls
    • New cough, unexplained weight loss, or ongoing chest symptoms
    • Possible treatment side effects or signs of infection
  3. 3

    Does any of this apply?

    Book an appointment

    Arrange a medical appointment if you develop gradually worsening leg weakness, repeated difficulty rising from a chair, unexplained dry mouth with weakness, or new problems with balance.

    These symptoms have many possible causes and need assessment rather than self-diagnosis.

    Routine changes in stamina or mild symptom fluctuations can usually be discussed at scheduled follow-up, unless they are worsening quickly or affecting breathing or swallowing.

Every sign above is quoted from the sofidex article on Lambert-eaton myasthenic syndrome. If you are not sure, err upward — it is always reasonable to be checked.
