Ankle injury without fracture, has been in a cast for 10 days, walking back pain should be normal. The ankle injury did not cause any fracture, but may have caused ligament damage or damage to the surrounding soft tissues. It will take some time for the ankle to fully heal after being braced in a cast. If there is an incomplete rupture of the ligament, it usually takes more than 4 weeks to heal completely, so in about 10 days, there will still be pain when walking out of bed. If there is a serious contusion of the surrounding soft tissues, it is not possible to recover completely after 10 days or so, and the pain will also appear when walking. It is important to note that until the doctor recommends removing the cast, it is recommended that the affected foot does not touch the ground even when walking to avoid aggravating the injury or affecting recovery.
