The finger movements are controlled by the tendons. The tendons are connective tissue cords that connect the finger bones to the muscles in the forearms. If the finger tendons are overloaded by lifting objects that are too heavy or lifting too quickly, this can result to inflammation of these tendons which is broadly described as tendinitis.
Micro tears can also develop in the tendon. Overusing the muscles that move the fingers can also lead to pain and inflammation. Remember that this type of injury is also called as tendinitis, but it is better described as tendinopathy. A doctor should be consulted so that an accurate diagnosis can be given if the individual experiences symptoms of finger tendinitis.
Pain and swelling
Hand tendinitis is considered as a sore condition. In most cases, the pain can be described as achy, sharp or there is a burning sensation that can be felt. The sensation of pain increases when the affected hand is used and usually reduces if allowed to rest.
Tendinitis typically develops in the tendons that are responsible for bending the fingers. In most cases, there is pain felt on the front aspect of the finger or along the length of the tendons as it travels throughout the palm, especially while engaging in certain activities such as typing or gripping. If there is direct pressure on the tendon such as holding a pen, it can also trigger pain. The swelling can develop over the tendon which causes a small-sized area that is puffy in appearance on the palm or finger.
Catching or popping
The tendons of the fingers glide through the tunnels in the hand as the fingers move. If tendinitis develops, it can cause the finger tendons to swell, thus making it difficult for the tendons to glide through these tunnels.
In severe cases of tendinitis, it can result to a condition called trigger finger in which the tendon of the affected finger is stuck or caught in the tunnel as the finger bends. When straightening the finger, there is a sore popping sensation as the tendon glides via the tunnel. Remember that trigger finger is one of the common diagnoses by many doctors. A doctor should be consulted if these symptoms are present since medical care might be needed.
Weakness and stiffness
The inflammation due to hand tendinitis can affect the hand strength and capability of the individual to move his/her fingers. Certain activities that involve the hands such as holding a door knob, holding a pencil or taking out a can of milk from the refrigerator can be difficult. In some cases, the individual might even drop objects.
Symptoms that are persistent can also lead to stiffening of the finger joints, thus affecting the ability of the individual to create a fist or completely straighten out the fingers. Prompt treatment for hand tendinitis can minimize the risk for developing these symptoms.
