SymptomsBy Mayo Clinic staff
Myelofibrosis usually develops slowly. In its very early stages, many people don't experience signs or symptoms. But as disruption of normal blood cell production increases, signs and symptoms may include:
- Feeling tired, weak or short of breath, usually because of anemia
- Pain or fullness below your ribs on the left side, due to enlarged spleen
- Enlarged liver
- Pale skin
- Easy bruising
- Easy bleeding
- Excessive sweating during sleep (night sweats)
- Frequent infections
- Bone pain
When to see a doctor
Make an appointment with your doctor if you have any persistent signs and symptoms that worry you.
