Hemophilia is a congenital X-linked hemorrhagic disorder. Its most frequent sign is an uncontrollable and prolonged bleeding, that results from lack or absence of some coagulation factors in the blood. Hemorrhage can occur even without any obvious cause. This bleeding often happens in joints. The symptoms include: 1. Bruising: the bruise resulted from little injuries that can result in a big hematoma, and 2.Bleeding: nose bleeding or bleeding in the mouth or gingiva, teeth brushing, bleeding after a minor cut and or dentistry operations; Joints are one of the common parts affected by bleeding in hemophilic individuals; Bleeding in the joints can make the joints swollen and painful. It also causes loss in the joints movements, deformities and resulting staggering and possible joints deformity; Bleeding inside the muscles makes the muscles swollen, hot to touch and painful. Swollenness resulted from bleeding in these areas can cause prolonged injuries and deformation through increasing the pressure on the tissues and the nerves.
