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.
An ankle sprain can cause both the ankle and foot to become red and swollen, as can a fracture in the foot or ankle. A dislocation in the ankle or foot may cause the foot and ankle to become red and swollen. There will also be pain at the site of the injury.
