Multiple Myeloma Symptoms


As myeloma cells divide and increase in number, they can affect the body in various ways.

Symptoms can include:

  • bone pain or fractures, including compression fractures of the spine, which can cause severe pain, particularly in the back
  • a backache that lasts for months, which can signal that multiple myeloma is affecting the bones in the spine or the ribs
  • frequent infections, especially bacterial infections of the respiratory or urinary tracts, which occur because the immune system is weakened
  • fatigue, weight loss, or general discomfort caused by anemia (insufficient red blood cells)
  • nausea, vomiting, an altered mental state, depression, or headaches, caused by an abnormally high calcium level in the blood (hypercalcemia)
  • changes to the kidneys that cause fatigue, a buildup of fluid in the lower limbs, nausea, or vomiting
  • bruising, rashes, nosebleeds, vision loss, headaches, dizziness, or numbness, tingling, or a burning pain in the hands or feet (peripheral neuropathy), caused by blood that has thickened due to a high level of proteins
  • shooting pain in the arms or legs caused by a tumor in the spinal column pressing on nerves

About one-third of people affected by multiple myeloma have no symptoms. Routine blood tests detect their elevated levels of immunoglobulin proteins at the time of diagnosis.
