That sounds really uncomfortable and understandably alarming! A swollen thumb with a bone that appears to be protruding is something that needs medical attention right away — please reach out to your doctor or go to urgent care today.

Lupus can definitely cause hand and finger swelling, and joint inflammation is very common. Close to 95% of people with lupus experience some form of joint pain or stiffness. When lupus causes ongoing joint inflammation, it can sometimes lead to a condition called Jaccoud's arthropathy, which causes visible changes to the joints in the hands over time. A MyLupusTeam member once shared, "When I first got sick, every joint hurt so bad, and my hands and feet were so swollen that I couldn't wear shoes or walk. My hands were like sausage fingers."

However, a bone visibly sticking out could also suggest something like a dislocation or fracture, especially since lupus and long-term corticosteroid use can contribute to bone loss.

Here's what to keep in mind:
- Don't try to push the joint back yourself
- Avoid using that hand until evaluated
- See a doctor as soon as possible — same day if you can

Your rheumatologist or an urgent care provider can assess whether this is lupus-related joint changes or something that needs more immediate treatment.
