Hard bumps that form on the finger joints closest to the nails are commonly caused by osteoarthritis, especially in older adults.
One classic sign is the development of Heberden’s Nodes, which are hard, bony enlargements of the joints nearest the fingertips.
Why might they seem to be spreading?
Osteoarthritis is a degenerative joint condition that can affect multiple finger joints over time. As more joints develop cartilage wear and bony changes, additional bumps may appear on other fingers.
Common features
- Hard (not soft) bumps near the nails
- Joint stiffness, especially after rest
- Reduced finger flexibility
- Occasional pain or tenderness
- Gradual development over months or years
Other possibilities
Although osteoarthritis is common, other conditions can sometimes cause bumps on the fingers, including:
- Rheumatoid Arthritis
- Gout
- Mucous cysts near the nail
- Other joint or skin conditions
When to see a doctor
It would be a good idea for your grandmother to be evaluated if:
- The bumps are growing rapidly.
- There is significant pain, redness, or warmth.
- The joints are becoming severely deformed.
- She is losing hand function.
- The diagnosis is uncertain.
Important note
I can’t diagnose the cause from a description alone. If you’d like a more specific opinion, upload a clear photo of the bumps. I can help identify common possibilities and explain what features doctors look for, though a healthcare professional would still be needed for a diagnosis.
