Hello Friend .. Welcome to Health Care Magic .. I read your query to Health care and it is quite normal for everyone to show symptoms of redness , rise in temperature and even ankle will be swollen because of ankle sprain .. Its Normal Process after injury to ankle .. Swelling requires 4 weeks time to get back to normal state . I suggest your mother to have complete rest to ankle. She may need to use crutches until you can walk without pain. For at least the first 24 to 72 hours or until the swelling goes down, apply an ice pack for 10 to 20 minutes every hour or two during the day. Always keep a thin cloth between the ice and your skin, and press the ice pack firmly against all the curves of the affected area. An elastic compression wrap, such as an ACE bandage, will help reduce swelling. You wear it for the first 24 to 36 hours. She also need a brace to protect ankle if she tries to put weight on it. Elevation of ankle above the level of your heart for 2 to 3 hours a day if possible. This helps to reduce swelling and bruising. I suggest Tablet Ibuprofen and Seratiopeptidase to reduce pain and swelling of ankle . Hope this information is helpful . Wishing her a speedy recovery .. Thanks & Take Care.
