If you suspect you have a sprained ankle, it is important to rest and immobilize the ankle for a few days. You should also try to limit the weight you put on it and apply heat to help with flexibility. Over-the-counter creams like Voltaren™ Emulgel can also be helpful in reducing pain and inflammation. If there is no improvement after 7-10 days, it is recommended to see a doctor for further evaluation and treatment.
