Ankle swelling can be caused by various factors, some of which may require medical attention. While it is not possible to provide a definitive diagnosis without a proper examination, there are several potential causes for ankle swelling. It could be due to fluid retention, injury or trauma, venous insufficiency, or even an underlying health condition such as heart or kidney problems. If the swelling is accompanied by severe pain, redness, warmth, or difficulty walking, it is advisable to seek immediate medical attention as these symptoms may indicate a more serious condition such as deep vein thrombosis (DVT) or infection. In the absence of these alarming symptoms and considering your upcoming doctor's appointment next week, you can monitor the swelling closely in the meantime. Elevating your legs when sitting or lying down and avoiding prolonged standing or sitting can help reduce swelling. Applying ice packs and wearing compression stockings may also provide relief. However, if the swelling worsens or persists beyond a few days despite these measures, it is important to consult with your healthcare provider for further evaluation and appropriate treatment options.
