A common injury that results in bleeding below the skin is called bruise. Generally bruises do not bleed. The skin develops a red color immediately after it is bruised. Later it becomes purple and after a few days it turns green and heals.
Bruise is a common problem in the older generation as the skin becomes thin which leads to easy bruising. People who take blood thinner medications also suffer from bruises. Athletes and weight lifters suffer from bruises as the micro blood vessels break during vigorous exercise leading the bruises. When a person bumps into any hard object there is a possibility of bruising. When a person develops sudden bruises it may be due to internal bleeding.
Those who are taking blood thinner and get bruise should immediately seek medical attention. If bruises happen often then it is time to seek medical help. Bruises near the head and eye also require immediate medical attention. Bruise with swelling and pain could be a fracture and hence should be dealt by a doctor.
Concussions on the head with or without a black out means head injury and should be diagnosed by a doctor to avoid any further complications.
Doctors may prescribed for x-rays if they feel that there may be a fracture. Continuous bruises over a period of time may be due to internal bleeding and a blood test will determine the condition. If bruises are over a period of time and at various stages of healing it may be due to physical abuse, which a doctor may suspect.
Some bruises can be treated at home using cold compress while it is still red. The compress should be wrapped in towel and not applied directly to the skin. If the bruise is on the leg, then keeping the leg in upward position for 24 hours will heal any swelling. Medications like Acetaminophen can help in healing, aspirins should not be taken during this time as they slow down the process of healing. After 48 hours heat treatment or applying of cloth dipped in hot water to the bruised area will help in fast healing of the bruise.
Sportsperson and children can avoid bruises by taking some precautions. Some of the common precautions are wearing protective gear while playing sports like cricket and softball. At homes, proper placement of objects can avoid fall. Electrical appliances and cords should be kept away from places where people walk frequently.
Bruises are indeed small injuries and require 10 to 2 weeks to heal.
