Radiation is a carcinogen and causes numerous effects on living organisms and systems. The environmental impacts of nuclear power plant releases such as the Chernobyl disaster, the Fukushima Daiichi nuclear disaster and the Three Mile Island accident, among others, persist indefinitely.
Ankle pain is most commonly caused by a sprain. A sprain is an injury to the ligaments connecting the ankle bones. Treatment of sprains includes using crutches, applying ice to the ankle, elevating the foot, using compression bandages, and taking over-the-counter pain relievers.
Ankle sprains occur when the tendons that stabilize the ankle joint are stretched too far, causing hyperextension, tears or complete detachment of the tendon from the bone. Time spent on crutches for a sprained ankle depends on the severity and the type of sprain.
