A hard lump on the top of the hand near the wrist is something many people with RA experience. There are a couple of likely explanations worth knowing about.
One possibility is a rheumatoid nodule — a firm, flesh-colored lump that forms just under the skin. These are the most common skin-related symptom of RA, affecting around 25–40% of people living with it. They tend to appear in areas that experience repeated pressure, like the fingers, hands, and wrists.
Another possibility is a soft tissue lump related to RA joint inflammation — specifically, a lump on the back of the hand that shifts when you straighten your fingers. This is a recognized RA hand symptom caused by tendon inflammation. Here's what to keep in mind about rheumatoid nodules:
- They are usually firm and round, and may shift slightly when pressed
- They don't typically cause pain, but can become tender if they press on nerves or grow large
- They are more common in people who test positive for rheumatoid factor (RF)
- In rare cases, methotrexate can speed up nodule growth — a side effect called accelerated nodulosis
It's always a good idea to mention any new lumps to your rheumatologist, especially if the lump becomes red, warm, painful, or starts to restrict your movement. They can confirm what it is and whether any treatment is needed.
