During the first 4-8 weeks, it is expected that there may be pain. This pain occurs in the back area with inflammation and certain redness. Weakness and lameness are also common when you walk after removing the orthosis. In many cases, recovery after an Achilles tendon surgery can take about 8-12 weeks. If you want to reduce the pain after the surgery, the doctor can give you a pain reliever. You can also apply an ice pack on the surface area of the leg for 10 minutes to decrease the swelling and pain.
