The ankle sprain occurs when the strong ligaments that support the joint are stretched and torn. Ankle sprains are common injuries that occur in people of all ages. These range from mild to severe, depending on the damage to the ankle ligaments.
Most are minor injuries that are treated with home remedies such as rest and ice application. However, if your ankle is too swollen and sore to walk - or if you have trouble putting your foot down, be sure to see your doctor.
Without proper treatment and rehabilitation, a more severe sprain can weaken your ankle, making you more likely to injure it again. Repeated ankle sprains can lead to long-term problems, such as chronic ankle pain, arthritis and continued instability.
