** 1. since you are a diagnosed case, [thus your doctor must have ruled out other conditions that affect muscles e.g: hypothyroidism, lupus, scleroderma, rheumatoid arthritis, toxin exposure, drug reactions, and genetic disorders), thus myositis is an autoimmune disease which causes inflammation of its own healthy muscle tissues, resulting in progressive weakness of muscles. [hopefully relevant investigations like CK enzyme test, EMG [electromyelography] and MRI has been conducted to identify the pattern and inflammation of the muscles concerned] 2.

To help prevent these illnesses: . get a flu shot each year, thoroughly cook meat, injection site should be clean [if any prescription drug is injected], routine blood tests to look for drug-induced muscle injury may be helpful as well. 4.

Regular stretching exercises can help maintain range of motion in weakened arms and legs. Physical therapy may also help prevent permanent muscle shortening, you may add whirlpool baths, heat and gentle massage. . Getting enough rest is an important component of managing myositis.
