Thrombocytopenia means you don't have enough platelets, cells in your blood that stick together to help it clot. It might not cause you any health problems at all. But if you do have symptoms like bleeding too much, treatments can help.
Call 911 for immediate emergency medical help if you have any of these symptoms:
Lengthy, uncontrollable bleeding -- either heavy or oozing in nature -- particularly after injury, immunizations or surgical or dental procedures
Any signs of internal bleeding, such as a change in consciousness, alertness, or memory or difficulty breathing (note that these symptoms may also be signs of other medical problems unrelated to hemophilia)
Call your doctor if you notice any of these symptoms:
Any episode of bleeding unrelated to a particular injury or event
Pain, swelling, warmth, or redness in a joint or muscle
Also talk to your doctor if you have a family history of hemophilia and are planning a pregnancy or expecting a baby.
