Some of the migraines I've had definitely rank right up there with that back sprain. The only thing in their favor is that, for me, they seldom last more than six hours and so I can focus on that thought as I lay there in total agony. A bad gout flare shoots up pretty high on the list, too -- I was shocked at how incredibly painful that is. I think I'll take a good ball kicking over migraines or gout or back sprains any day, despite how much pain is involved in that little endeavor.No judgement here... After I posted, it occurred to me that the migraines I get on a weekly (sometimes daily) basis are sometimes bad enough to make that short list. But that's so commonplace to me that it didn't come to mind. I've had some muscle cramps too that I swear I was only moments away from my muscle separating from the bone. Getting kicked in the balls hurts pretty bad too.
