My heel is killing me!!!!

Look, I’m not exactly an athlete—I haven't taken any wild falls or sustained some dramatic sports injury. There isn't any swelling, and it isn't turning red or anything obvious like that, but my left heel is throbbing with such intensity that I can barely even stand up... what on earth is happening? Is this one of those things where we start talking about amputation, or am I just spiraling into a million different health anxieties I've made up in my own head?

It usually boils down to two things: you’re either dealing with a classic heel spur, or that pain in your foot is actually just radiating down from your lower back.
