Possible Myositis?

@Bethanya Myositis is a condition in which your muscles actually deteriorate. It typically effects the biceps and thighs. Some forms are treatable but also come with high risks of cancer and other forms are not treatable but less severe. All forms tend to debilitate to the point of needing assistive devices such as wheelchairs and walkers. To diagnose, it requires a muscle biopsy. It is very similar to muscular dystrophy. It is not a symptom but an entirely rare disorder on its own.
