I sprained my ankle on 24th Aug. I was able to walk on it immediately after but it became very swollen and slightly painful to walk on a few hours later. For the next few days I followed RICE methods. There was little pain and the swelling was reducing but I was unable to walk normally still. I had to take a long-haul flight on 31st aug for a conference and have had to walk around more since then. Now (8th sept) my calf has been quite swollen and painful for the past 3-4 days. Please advice
