If you are experiencing significant pain in your ankle and foot when walking, it is important to determine the cause of the pain. This could be due to various factors such as overexertion during exercise, a specific activity, an injury, or wearing new shoes. It's important to evaluate if there are any other symptoms such as swelling or redness. Additionally, applying ice wrapped in a damp towel or a bag to the affected area for 10 to 15 minutes several times a day may help alleviate the pain. In cases of injury, it is advisable to seek help from a physiotherapist who can assess the pain and create a treatment plan to help heal the injury and prevent future ones. Many health insurance plans cover this type of service.
