As people age, the body naturally changes, and some of these changes can feel unexpected or even concerning. One common issue is the appearance of hard bumps on the finger joints, especially near the fingertips. These bumps may look unusual and sometimes cause discomfort, leading many to wonder what they mean and whether they signal a serious problem.

If your grandmother is experiencing this, she's not alone. These bumps are actually quite common—and in most cases, they're a sign of osteoarthritis, not something more alarming.

Let's explore what these bumps are, why they appear, and what can help.

What Are These Bumps?

In most cases, these bumps are known as nodes and are commonly associated with osteoarthritis. Osteoarthritis is a condition in which the protective cartilage in the joints gradually wears down over time. When this cushioning decreases, the bones begin to rub against each other. In response, the body forms extra bone as a way to stabilize the joint, which results in the hard, raised bumps seen on the fingers.

There are two common types of these finger nodes:

Type	Location	Associated With
Heberden's nodes	The joint closest to the fingertip (distal interphalangeal joint)	Most common form
Bouchard's nodes	The middle joint of the finger (proximal interphalangeal joint)	Also osteoarthritis
