I'm wondering which is worse--constant pain, or pain that comes in waves. Right now, I'm thinking it's the latter. If you're constantly in pain, you're almost able to reprogram your brain to get used to it and not to expect anything more. Whereas when pain comes in waves, you never know when it'll hit. It comes out of nowhere and blindsides you, paralyzing you for awhile. And when that happens on a day when you're actually feeling okay with things, it hurts SO MUCH MORE than when it's constant.
