A few days a go my heel began to hurt, I thought I saw something black in the middle, I got some twizers and tried to get it out, but then it had totally gone in by then. So my foot's been hurting ever since. First it was just my heel that hurt, then my lower leg now my thigh, and my back. It's not a "oh-death-death" kind of pain, but more a nagging annoying pain that persists and starts to really bother you after a while (the first few days I couldn't walk properly).
