PATHOLOGY

Detailed explanation-1: -Swelling is the result of the increased movement of fluid and white blood cells into the injured area. The release of chemicals and the compression of nerves in the area of injury cause pain. The pain and swelling can keep the athlete from using the injured part, serving to protect it from further injury.

Detailed explanation-2: -Some of the many common causes of fluid retention include: Gravity – standing up for long periods of time allows fluid to ‘pool’ in the tissues of the lower leg. Hot weather – the body tends to be less efficient at removing fluid from tissues during the summer months. Burns – including sunburn.

Detailed explanation-3: -After an injury, the body identifies the injured area and sends many white blood cells to the area to start the healing work. This reaction is also associated with extra blood flow to the area, which can cause heat and redness. This increased fluid in the area causes swelling and thus pain.
