###Human: I have swelling and pain in elbow area after an accident. Why? ###Assistant: Hello. There must be crushing of the tissues and what is called internal degloving and a collection of blood called a hematoma and that causes the part to be swollen and warm to touch. As long as there is no fracture then you do not need a plaster but a sling to rest the arm is mandatory till the pain comes under control and the swelling reduces.  The sling will also enforce rest to the part and will help keep the forearm from swelling up. Ice the arm and elbow 20 minutes for five to six times a day. Elevate when in bed on two pillows. If no better in a week then re-visit a doctor for a review.
