As we grow older, the body experiences many changes, and some can feel unexpected or worrying. One fairly common change is the development of firm, hard lumps around the finger joints, particularly those near the fingertips.
These bumps can look unusual and may sometimes be accompanied by pain or stiffness, causing people to wonder what they are and whether they could indicate a serious health condition.
In many situations, these lumps are bony enlargements linked to osteoarthritis, a common type of arthritis that occurs as the cartilage protecting and cushioning the joints gradually becomes thinner and less effective.
When these bumps appear on the joints nearest the fingernails—the distal interphalangeal, or DIP, joints—they are generally known as Heberden’s nodes. Similar bony growths that form on the middle joints of the fingers are called Bouchard’s nodes.
Why Do These Bumps Develop?
Healthy cartilage helps the bones within a joint glide smoothly past each other. With osteoarthritis, this protective layer of cartilage slowly deteriorates. As changes occur within the joint, the body may form extra bone along its edges, creating small growths called bone spurs.
