Living with Acute flaccid myelitis
A condition of the spinal cord that causes sudden muscle weakness and loss of reflexes, often after a viral illness.
Understanding Acute flaccid myelitis
Most people who develop AFM had a viral illness with flu-like symptoms one to four weeks before. Many people continue to have muscle weakness for months to years. Sometimes the muscles used for breathing weaken, and a ventilator is needed to help with breathing.
Signs & symptoms
Symptoms vary from person to person. GARD's summary says they include:
- Sudden weakness in an arm or leg
- Loss of muscle tone
- Weak or missing reflexes
- Pain
- Weakness in the face
- Trouble swallowing, speaking, or moving the eyes
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
