Excruciating I voted excruciating I got my first flare up over two years ago. My tailbone was swollen to the size of a baseball. I took pain meds and felt like they did nothing, had it lanced the next day. Here I am two years later and 6 days out of open-wound surgery. I had several flair ups between no and then. I've had a broken finger, spiral-fractured a bone in my hand, had kidney stones twice, and I must say: This is the worst. Kidney stones are about equal in pain, but PC has more discomfirt with it due to it being inside and outside the body in a way. To you women who have said its worse than childbirth - I believe you!
