If the heel slides are causing pain then they are not helping you. Remember the beginning of our guidelines, “if it hurts, don’t do it.” Here is how to properly do a heel slide: https://bonesmart.org/forum/threads/heel-slides-and-how-to-do-them-properly.26903/ which is also in the guidelines. And actually, you don’t even have to do any heel slides, especially this early. Time and healing will take care of things. This is because: It’s not exercising that gets our range of motion back, it’s Time: Time to recover. Time for pain and swelling to settle. Time to heal. Our range of motion is right there all along just waiting for that to happen so it can show itself. In the general run of things, it doesn't need to be fought for, worked hard for or worried about. It will happen. Exercise as in strength training is counter-productive and in the early weeks does more harm than good. Normal activity is the key to success.
