What should you know about multiple myeloma and rheumatoid arthritis?

Rheumatoid arthritis is an inflammatory autoimmune condition that commonly presents with joint pain, joint swelling, and stiffness, often involving the hands and feet. Multiple myeloma is a blood and bone-marrow cancer with a different pattern of evaluation. Symptoms can overlap, but they are not interchangeable diagnoses. Finger stiffness, hand swelling, and morning joint stiffness are useful details to report, along with fatigue, recurrent infections, bone pain, or unexplained changes in general health.

Make an appointment with your clinician or rheumatology team if swelling or stiffness persists, affects several joints, or limits ordinary tasks. Bring a symptom timeline, family history, current medicines, and any previous blood tests or scans. The evaluation may include an examination and tests selected for the pattern of symptoms. Do not start, stop, or share anti-inflammatory medication without checking first, especially if you have kidney, stomach, blood, or bone-marrow concerns.

Seek prompt care for severe new bone pain, a suspected fracture, marked weakness, confusion, chest symptoms, high fever, or a rapidly swollen hot joint. Emergency assessment is appropriate for sudden loss of movement, severe pain after a minor injury, or symptoms suggesting a serious infection.
