In a person with back pain, and low hemoglobin, we need to exclude multiple myeloma a cancer of bone marrow, which can be done by doing blood tests, such as serum protein electrophoresis, urine Hence Jones protein, etc. At present, you need not worry, as a diagnosis has not been reached for any serious disease. I hope it helps. Please get back if you require any additional information. Wishing you good health,
