Injury
When you have an injury on your ankle, it might lead to inflammation and swelling. In these cases, swelling is a normal symptom indicating that your immune system is working to fight against foreign invaders. One of the most common forms of ankle injuries is an ankle sprain. Fortunately, it is not a serious health issue. You can treat some mild cases with simple home remedies, such as wearing ankle braces, resting, elevating the feet, applying compression wraps, or using ice packs. [3]
