What are the symptoms of finger tenosynovitis?

Punctures and bruises on the fingers in daily life may cause tenosynovitis, resulting in many adverse symptoms such as redness, swelling, pain and heat. In severe cases, the patient may even lose the ability to work. In this case, you must go to a regular hospital for examination and treatment. You can also increase the amount of finger activities on your own in daily life, and the symptoms will be significantly relieved.

1. Causes of finger tenosynovitis

Finger tenosynovitis often occurs on the palm side of the fingers. Each tendon on the palm side of the hand has a sheath. When the tendon sheath is injured and damaged, allowing bacteria to invade the sheath, tenosynovitis occurs. The causative bacteria are mostly Staphylococcus aureus, which is mostly caused by injuries such as punctures, bruises, hangnails or cutting the nails too deep.

The tendon sheath has the function of maintaining normal flexion and extension of the fingers and tendon sliding. When the hand is fixed in a certain position and subjected to repetitive and excessive activities, friction often occurs between the tendon and the tendon sheath, resulting in edema and fibrosis, causing narrowing of the inner cavity. Tenosynovitis is a condition in which pain and movement disorders occur due to the narrow path through which the tendon moves within the tendon sheath.

2. Symptoms of finger tenosynovitis

It often occurs on the palm surface of the finger. The affected finger will appear red, swollen, painful, and hot, and will be in a flexed position, because straightening the finger will cause pain. If not treated in time, after the purulent infection, tendon necrosis will cause the fingers to lose their function of movement, and the pus may also flow into the adjacent finger tendon sheaths and palm gaps, causing complete disability of the hand. The patient feels generally unwell, with chills and high fever.

Use the right thumb to press the painful area of ​​the left hand, and then use the left thumb to rub the painful area of ​​the right hand. Press whenever you have time. If you persist for several months, you will be cured.
