You may have to wear a cast until your bone heals within 6-8 weeks. You're not allowed to put weight on your broken ankle and only do simple exercises while lying or sitting down. Your doctor will request you to do physical therapy and rehabilitation as soon as your bone recovers. It is necessary to get one post-injury to help you learn how to walk again. If you have no problems with your overall health, you may expect a fast and smooth recovery. However, watch out for occurring symptoms like fever, intense swelling, severe pain, and/or stiffness of your injured ankle as these may be signs of complication. You may also develop long-term effects like arthritis, limping when you walk, and deformity in your injured foot. If you're recovering from an injury, do not push yourself too hard to get up from that bed. It will get better in time so, don't rush because the last thing you want is to break your broken ankle again. Please listen to the advice of your doctor. You also have the right to discuss your recovery timeframe with them.
