Summary Summary. Listen. Myelofibrosis is a disorder of the bone marrow, in which the marrow is replaced by fibrous (scar) tissue. When the bone marrow is scarred, it cannot make enough blood cells. This leads to anemia, weakness, fatigue, and often, swelling of the liver and spleen.
Some symptoms of myeloma includeâ: 1  Bone pain and/or skeletal fractures. Bone pain is the most common early symptom of myeloma. 2  Fatigue and weakness as a result of low red blood cell counts (anemia). Myeloma patients may fatigue more easily and feel weak. 3  Frequent infections due to a weakened immune system.
