If you still have pain after several months of foot sprain, you should get an MRI of the ankle as soon as possible to determine if there is a missed or misdiagnosed diagnosis. It is likely that there is ligament damage or ligament rupture in the ankle joint. In this case, the first step after the ankle sprain is to apply brakes, i.e., to avoid activity. The first step is to go to the hospital to take an X-ray to rule out a fracture. If there is no fracture, the cast should be fixed for 2-3 weeks and then removed after the swelling and pain have disappeared and functional exercise of the ankle joint should be performed. If the pain in the ankle joint is still heavy when the cast is removed for functional exercise or walking, there is still significant localized pressure pain or percussion pain. An MRI should be performed at the first opportunity to determine whether there is a ligament rupture or tear. If the ligament rupture or tear is confirmed, surgery should be performed as soon as possible for complete recovery.
