Multiple myeloma is a cancer of plasma cells that typically presents with bone pain, fatigue, and recurrent infections due to the buildup of abnormal proteins. Because multiple myeloma affects the bone marrow, symptoms often include unexplained fractures, anemia, and kidney impairment, which vary significantly in severity based on individual disease progression. What are the most common symptoms of multiple myeloma? The clinical presentation of multiple myeloma is often summarized by the "CRAB" criteria, which represent the most frequent complications.

Multiple myeloma is a cancer of plasma cells that typically presents with bone pain, fatigue, and recurrent infections due to the buildup of abnormal proteins. Because multiple myeloma affects the bone marrow, symptoms often include unexplained fractures, anemia, and kidney impairment, which vary significantly in severity based on individual disease progression.
The clinical presentation of multiple myeloma is often summarized by the "CRAB" criteria, which represent the most frequent complications. These include:
Early symptoms of multiple myeloma can be subtle and easily mistaken for common age-related issues. Watch for persistent, localized bone pain that does not resolve with rest, frequent unexplained infections, or sudden onset of extreme fatigue. Routine blood work may reveal elevated protein levels or anemia before significant bone damage occurs.
As multiple myeloma progresses, the accumulation of malignant plasma cells can lead to spinal cord compression or peripheral neuropathy. Chronic pain and mobility issues are the primary factors affecting the quality of life for the 217 community members on DiseaseMaps.org living with this condition. Symptoms often fluctuate; however, consistent monitoring is essential as the disease evolves through different clinical stages.
You should seek emergency care if you experience sudden, severe back pain accompanied by numbness or weakness in the legs, which may indicate spinal cord compression. Additionally, signs of hypercalcemia, such as severe confusion, extreme lethargy, or inability to keep fluids down, require urgent medical evaluation.
