Your Finger Joint Pain is Probably Caused by Arthritis

Since your fingers are being used constantly, they are at higher risk for pain and injury. Finger pain and soreness are caused by a change in the structure of your blood vessels, joints, tendons, bones, muscles or connective tissues. If your finger joint is swollen, stiff, or painful you most likely have a form of arthritis in your fingers. If you live in the United States, it is highly likely that you have heard of Arthritis, the inflammation of joints. With over 100 specific types, Arthritis is the most common chronic illness in the U.S.

To better understand where your pain may be coming from, it’s important to have a grasp on how your fingers function. Your finger is constructed of three main parts: ligaments, tendons, and bones. Surprisingly, there are actually no muscles in your fingers. You must be thinking… How are my fingers able to move then? Well, the muscles of your forearm pull on the tendons in your fingers, allowing them to move.

Finger Anatomy 

There are three different knuckles in your fingers. The knuckle between your hand and your finger is called the metacarpophalangeal joint (MCP). This knuckle is most commonly injured in closed-fist activities. The next knuckle, located in the middle of your finger, is called the proximal interphalangeal joint (PIP). The most common injuries for this knuckle occur during sporting events when an object strikes the finger directly. The third knuckle, nearest to your fingernail, is called the distal interphalangeal joint (DIP). This typically involves a fracture of a torn tendon if there is an injury. If you are experiencing finger joint discomfort and pain, it’s important to identify the where it’s coming from. Let’s take a closer look at forms of arthritis that may be causing this pain.

What’s the Difference Between Joints and Knuckles in your Fingers?

Osteoarthritis is the common form of arthritis and affects over 20 million people in the United States. This form of arthritis is caused by the breakdown of cartilage. Cartilage is the cushion in between the bones of the joints. When this cartilage breaks down, the bone becomes swollen. This can lead to a bone spur in the joint.
