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.
The most common symptoms of myelopathy include neck stiffness, deep aching pain in one or both sides of your neck and possibly your arms and shoulders, and possibly stiffness and weakness in your legs and difficulty when walking. You may also feel a grating or crackling sensation when you move your neck.
