I have a "straddle injury" (blunt force trauma to pelvic region) that resulted in a large hematoma of my right labia majora (vulva). After three weeks, the initial swelling and bruising which extended in a triangle from perinium to pubis to hip bone has resolved, but there is still a large blood clot mass in the vulva. The size is about the size of an egg. Conservative treatment is to allow it to heal without surgical intervention due to the risk of infection. How long should it take for the blood clot to substantially reduce in size? Other than warm baths, loose clothing and time, is there an effective treatment to encourage more rapid healing?
