Most people with cryoglobulins have no symptoms other than elevated levels on specially ordered lab tests. When symptoms are present, they are most commonly fatigue, joint pain, numbness or weakness, and a particular rash called purpura that looks like red spots or purple bruises, usually over the lower legs.
Other symptoms and signs may include:
- Change of the color of hands and/or feet (from normal to white to a purplish-blue color) with cold, called "Raynaud's Phenomenon," but Raynaud's is very common in persons without cryoglobulinemia.
- Weight loss
- High blood pressure
- Swelling of ankles and legs
- Skin ulcers and gangrene
- Enlarged liver or spleen
- Numbness, tingling or weakness of hands or feet
- Kidney damage
