Hello, Thanks for your query. First line of treatment RICE therapy. RICE Therapy •Rest:Reduce regular exercise or activities of daily living as needed. Your health care provider may advise you to put no weight on an injured area for 48 hours. If you cannot put weight on an ankle or knee, crutches may help. If you use a cane or one crutch for an ankle injury, use it on the uninjured side to help you lean away and relieve weight on the injured ankle. •Ice:Apply an ice pack to the injured area for 20 minutes at a time, four to eight times a day. A cold pack, ice bag, or plastic bag filled with crushed ice and wrapped in a towel can be used. To avoid cold injury and frostbite, do not apply the ice for more than 20 minutes. •Compression:Compression of an injured ankle, knee, or wrist may help reduce swelling. Examples of compression bandages are elastic wraps, special boots, air casts, and splints. Ask your health care provider for advice on which one to use and how tight to apply the bandage safely. •Elevation:If possible, keep the injured ankle, knee, elbow, or wrist elevated on a pillow, above the level of the heart I do hope that you have found something helpful and I will be glad to answer any further query. Take care
