Common symptoms of multiple myeloma include:

• Frequent infections due to a weakened immune system (a person with myeloma is referred to as being immunocompromised)
• Bone pain (often in the back, ribs, and hips)
• Kidney problems
• Weakness due to anemia

Diagnosis:

The diagnosis of multiple myeloma is suspected by finding an elevated amount of certain antibodies in the blood and urine. A bone marrow biopsy and a bone marrow aspirate (using a needle for biopsy and a syringe to aspirate a small amount of bone marrow blood) are performed to confirm the diagnosis.
