Glossary Eosinophilia-Myalgia Syndrome

rare condition with high eosinophils and severe muscle pain

Eosinophilia-Myalgia Syndrome (EMS) is a rare and potentially serious condition characterized by high levels of eosinophils (a type of white blood cell) in the blood and severe muscle pain (myalgia). It was notably linked to the consumption of contaminated L-tryptophan supplements in the late 1980s. Symptoms can include muscle weakness, skin changes, and joint pain, and the condition may lead to long-term health issues if not properly managed.
