A swollen ankle may be caused by soft tissue injury or fracture of the ankle joint, which can be treated with physiotherapy, medication, or further examination and surgery if necessary. 1. Physiotherapy: cold compresses can be applied within 72 hours to reduce swelling, and hot compresses can be applied after 72 hours to promote blood circulation and speed up the swelling. You can also choose heat therapy, electrotherapy, magnetic therapy and other physical factors to speed up the recovery of swelling. 2. Physical therapy: swollen feet can be prescribed by the use of drugs such as non-steroidal anti-inflammatory analgesic drugs: ibuprofen extended-release capsules, etc., depending on the individual situation, you can choose to take orally or externally. When allergic reactions occur, stop the medication and consult a doctor. 3. Further examination: If the above treatment is ineffective or accompanied by deformity, abnormal activity, bone rubbing sound, etc., X-ray examination should be carried out in time to determine whether fracture occurs. If a fracture occurs, it should be treated according to the doctor’s instructions. If your foot is swollen, you should consult a doctor and choose the appropriate treatment after examination and evaluation to avoid serious consequences.
