### Patient: Doctor, I have been experiencing muscle swelling and my menstrual periods are lasting longer than usual. Also, one of my ears seems to be a bit abnormal in size and shape. What could be the reason for this? 
### Doctor: It is possible that you are suffering from Von Willebrand disease, which is a blood clotting disorder. This disease results in prolonged menstrual bleeding as well as abnormal bleeding after injuries or surgeries. The muscle swelling you are experiencing could also be a symptom of this disease. Additionally, some people with Von Willebrand disease may have physical abnormalities, such as an abnormally shaped or sized ear.
