About one-third of people with myelofibrosis (MF) have no symptoms at the time of diagnosis. Patients often learn they have MF after a routine physical exam and blood test.
When MF signs and symptoms do appear, they can include:
- Shortness of breath
- Weight loss
- Excessive night sweats
- Unexplained bruising
- An enlarged liver
- An enlarged spleen, which may cause discomfort, a feeling of fullness or a "dragging" feeling on the upper left side of your stomach
- Bone or joint pain
See your doctor if you're troubled by any of the above signs or symptoms.
