Mixed connective tissue disease is considered an overlap disease, because it has the symptoms of other disorders, including scleroderma, polymyositis and lupus.
The symptoms of different disorders often don't appear all at once. Instead, some of them occur at an early stage while others only show later. This makes diagnosis more difficult.
- Swollen hands or fingers. In some cases, the fingers may look like sausages.
- A fever and fatigue.
- Painful muscles and joints.
- Rash over the knuckles.
Unfortunately, the disease can't be treated. Medications are used to ease some of the symptoms.
