IPA: /ˌmaɪəˈsaɪtɪs/
KK: /maɪəˈsaɪtɪs/
A condition where a muscle becomes inflamed, causing pain and tenderness, often affecting voluntary muscles.
The doctor diagnosed her with myositis after she complained of muscle pain and weakness.
Myositis is formed from "myo-" (from Greek "musculus", meaning muscle) and "-itis" (from Greek "itis", meaning inflammation). The word refers to the inflammation of muscle tissue.
Think of 'myo-' relating to muscles and '-itis' indicating inflammation, so myositis means inflammation of the muscles.
