Human body consists of tendons, tough tissues that connects muscle to bone and is responsible for withstanding tension. Sometimes, the tendon around the thumb gets irritated and swollen due to various reasons and this condition is known as De Quervain's tendinosis. The word tendinosis in itself means the swelling of the tendons. Swelling and compression of the tendon can cause pain and tenderness around the thumb and you experience the pain while forming a fist, trying to grip something and when trying to turn your wrist.
However, the exact cause of this condition is not yet known, its cause is considered as any activity that depends on repetitive hand or wrist movement. These activities include doing household chores or working in the garden, playing, lifting things etc. All such activities can even worsen the pain in a person suffering De Quervain's tendinosis. This condition can further lead to Carpal Tunnel Syndrome in a person. It is a condition of hand and arm that causes numbness, tingling, weakness and other symptoms and is caused due to the pressure on the median nerve in your wrist. Various factors including structure of the wrist, certain health problems and possibly patterns of hand use contribute to this condition.
Carpal tunnel is a thin passageway surrounded by bones and ligaments. It is located on the palm side of the wrist protecting the main nerve of hand and the nine tendons that help bend fingers. Compression of the nerve due to pressure causes numbness, tingling and weakness in the hand. Symptoms of Carpal Tunnel Syndrome usually occur in the thumb, index finger, middle finger, and half of the ring finger. You can get relief by keeping your hand movement at rest. However, people suffering from this condition can get relieved with quick and proper treatment and can easily restore wrist and hand function actively.
