Is Mixed Connective Tissue Disease Painful?
Mixed connective tissue disease is an autoimmune disorder which has symptoms of other connective diseases. These symptoms are so mixed with each other; it is difficult to differentiate them. In this disorder, one's own immune system attacks its own connective tissue considering it to be an invader. It is a rare condition in which another connective tissue disorder develops slowly over a period of a few years. It occurs more in women than men. Its causes are not clear. Its symptoms include muscular pain, joint pain, fatigue, Raynaud phenomenon and others discussed below.
Is Mixed Connective Tissue Disease Painful?
In the early stage, mixed connective tissue disease affects hands and fingers. It leads to the swelling and pain in the fingers. The numbness and whiteness develop in the fingertips; occur due to cold exposure and stress. In the later stage, it may extend to the lungs, heart, and kidneys. It can also affect the blood, blood vessels, bones and muscles of the body.
When mixed connective tissue disease involves muscles, bones, nerves, etc., it causes pain and swelling in these parts. It is usually a painful condition.
The exact cause of mixed connective tissue disease us not known. The overactive immune system may attack the healthy tissues of the body. They destroy the fibers of the muscles and skin making them rigid and hard. It also causes the inflammation of proteins, namely collagen, and elastin. Genetic anomalies can also trigger mixed connective tissue disease. Usually, patients have a family history of mixed connective tissue disease.
Symptoms Of Mixed Connective Tissue Disease
The symptoms of mixed connective tissue disease are following-
- Joint pain
- Muscular pain without any apparent cause
- Low-grade fever
- Raynaud phenomenon- numbness, loss of color and sensitivity in fingers, ears, nose, and toes due to exposure to cold and stress.

Electromyogram is often used to record the electric activity in the nerves and muscles. Muscle biopsy is also done to evaluate the damage to the muscle fiber.
Treatment For Mixed Connective Tissue Disease
Mixed connective tissue disease is treated by corticosteroids to control the exaggerated immune system. This help in reduction in inflammation. There are other treatment options too.
Mixed connective tissue disease is a combination of connective tissue diseases such as systemic lupus erythematosus, and polymyositis. This condition is also called overlap disease as their characteristic symptoms overlap with each other. It is an autoimmune disease. In this condition, the representing symptoms are so jumbled that the doctors cannot diagnose a particular disease.

Mixed connective tissue disease is a group of disorders of connective tissue. It is a rare autoimmune disorder. Its symptoms are a combination of few connective tissue diseases that overlap each other difficult to differentiate. Mixed connective tissue disease can cause pain in the muscles or bones or joints, causing deformities and disability.
