Signs and symptoms of hemophilia vary, depending on your level of clotting factors. If your clotting-factor level is mildly reduced, you might bleed only after surgery or trauma. If your deficiency is severe, you can bleed easily for seemingly no reason. Signs and symptoms of spontaneous bleeding include:  Unexplained and excessive bleeding from cuts or injuries, or after surgery or dental work Many large or deep bruises Unusual bleeding after vaccinations Pain, swelling or tightness in your joints Blood in your urine or stool Nosebleeds without a known cause In infants, unexplained irritability  Bleeding into the brain A simple bump on the head can cause bleeding into the brain for some people who have severe hemophilia. This rarely happens, but it's one of the most serious complications that can occur. Signs and symptoms include:  Painful, prolonged headache Repeated vomiting Sleepiness or lethargy Double vision Sudden weakness or clumsiness Convulsions or seizures
