Could you tell me what happen after burst prolapsed hemorrhoid without treatment?

Usually bleeding . Bursting of hemorrhoids is equal to tearing open blood vessels. It may be able to stop on its own or surgery might be needed. If it stops, nothing else is needed. High fiber diet is the key to avoid more complications. Rarely, u can have infection and this may need antibiotics or surgery or both. If there is persistent pain, bleeding, fever/chills etc, u need to call ur doctor.
