Symptoms of multiple myeloma

The symptoms are caused by the localization of myeloma cells in bone marrow and the effect of the M-component (paraprotein).

  • Symptoms of bone disease are, for example, lasting inexplicable back pain
  • Reduced kidney function
  • Anemia, more rarely leukopenia and thrombocytopenia
  • Hypercalcemia due to osteolysis
  • Repeated or lasting bacterial infections due to reduced immune system
  • Hyperviscosity
  • Symptoms which indicate compression of the spinal cord/nerveroots 
  • Sign of amyloidosis, for example large tongue, carpal tunnel syndrome, kidney and/or heart failure
  • Prolonged elevated blood sedimentation rate as a coincidental finding.
