No need to freak out. Respect your pain, but don’t fear it. The way forward is to modify your training as much but also as little as necessary to keep the pain at or below an acceptable limit. This mean avoiding hills, or speed, or hard surfaces for the time being (these are just random examples to illustrate the point). Don’t take anything off the table unless common sense and symptoms tell you that you need to. I’ve been where you are MANY times and it almost always works out okay if you embrace the process I’ve just described. I call it scrambling (as in golf when you hit a bad tee shot and need to get creative to salvage par).
