Here are some of the main reasons this can happen:
- Joint inflammation — Nearly 95% of people with lupus experience joint pain or stiffness, which can cause swelling that affects how the whole arm or leg functions
- Muscle inflammation (myositis) — During a flare, muscles can become inflamed and sore, contributing to swelling and pain
- Fluid retention — General swelling in the extremities is a recognized lupus symptom
- Medication side effects — Some lupus medications, like corticosteroids and biologics, can cause pain or swelling in the arms and legs as a side effect
One MyLupusTeam member shared, "I can't raise my left arm. My arm and hand are pretty useless when this happens."
If swelling is new, sudden, or getting worse, it's worth checking in with your doctor or rheumatologist. They can help figure out the cause and adjust your treatment plan if needed.
