Get StartedSymptoms
By Mayo Clinic staffMyelofibrosis 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)
- Fever
- Frequent infections
- Bone pain
When to see a doctor
Make an appointment to see your doctor if you:
- Feel run-down or tired
- Have a feeling of unusual fullness in your left abdomen
- Experience unexplained weight loss
- Sweat excessively during sleep
- Have other possible signs and symptoms of myelofibrosis
These signs and symptoms, although vague, should be checked out by your doctor.
