What causes pain in right thumb

If you experience pain in the thumb of your right hand, you should pay attention and go to the hospital for examination in time. There are many reasons for this pain, the more common ones are rheumatism and thumb tenosynovitis, which are common causes of thumb pain. For example, thumb tenosynovitis is relatively common in life, which is closely related to thumb strain in daily life.

Causes may include injury, overuse (especially in the thumbs, hands, elbows and fingers), osteoarthritis, some immune diseases, or even infection. Some occupations that require long-term repetitive strain on joints, such as typists, keyboard players, instrumentalists, cargo handlers, or industries that require long-term computer operation, can cause or aggravate this disease.

Common affected areas include the wrists, fingers, shoulders, etc. Women and diabetics are more likely to develop this disease. Patients will feel joint pain and morning stiffness. Usually the feeling of morning stiffness is most obvious after getting up, and the symptoms will not be significantly relieved with frequent activities. The affected joints are swollen and even popping, and joint movement is impaired.

Clinical symptoms

Flexor tendon tenosynovitis often occurs in the thumb, ring finger, index finger, middle finger and elbow. The affected fingers have flexion and extension dysfunction, which is particularly obvious when waking up in the morning and can be alleviated or disappear after activity. The pain sometimes radiates to the wrist.

Flexion of the metacarpophalangeal joint may cause tenderness, and sometimes a thickened tendon sheath and a pea-sized nodule can be felt. When the affected finger is bent, it suddenly stays in a semi-bent position. The finger can neither be straightened nor flexed, as if it is suddenly "stuck", causing unbearable pain. With the help of the other hand, the fingers can move again, producing an action and sound like a trigger, so it is also called "trigger finger".

Closed treatment

It can relieve early-stage tenosynovitis and should be blocked once a week. Generally, blocking treatment methods cause greater damage to local tissues and are prone to recurrence. Severe patients can choose surgical treatment. Finger flexion and extension exercises should be performed early after surgery to prevent tendon adhesion, and manual labor should be avoided within 1 month after surgery.
