clinical features of hemophilia

Hemophilia is a rare, inherited bleeding disorder in which the blood doesn't clot normally. Here are the clinical features of hemophilia:

1. Bleeding into joints: This can cause swelling and pain or tightness in the joints; it often affects the knees, elbows, and ankles.

2. Bleeding into the skin (which is bruising) or muscle and soft tissue causing a build-up of blood in the area (hematoma).

3. Bleeding of the mouth and gums, and bleeding that's hard to stop after losing a tooth.

4. Bleeding after circumcision (surgery performed on male babies to remove the hood of skin, called the foreskin, covering the head of the penis).

5. Bleeding after vaccinations.

6. Blood in the urine or stool.

7. Frequent and hard-to-stop nosebleeds.

8. Prolonged or continued bleeding after bleeding previously stopped.

9. Unexplained and excessive bleeding from cuts or injuries, or after surgery or dental work.

10. Prolonged headache, repeated vomiting, neck pain, or has excessive sleepiness, as these can be signs of bleeding in the brain.

These symptoms can vary from person to person. Some people have few symptoms while others have more severe and frequent symptoms. The severity of symptoms can also change throughout a person's life.
