It's not like - when you're trying to get comfortable, and you flip the pillow over or pull your blankets closer. It's more like when you're trapped in a simple room with just you, and that feeling. Sleep won't even visit, and thirst and hunger have long since abandoned you. Just you, and this physical pain with no foreseeable end and no reason that you know of, for it's existing. At first you thought it could have been food poisoning. You realize for, not the first time, that your pulse is racing but you forget to breathe every couple of seconds. You lye in bed, on one side, the pain seems to lessen. You move, it burns. You become frustrated, and sit up on the edge of the bed. It hurts. You stand up, sit down, lean your head in your left hand, kind of doze off. Wake up, try the other side. It doesn't seem to work. The cat wonders what her human is up to, tries to snuggle, and get's gently pushed aside. You try to lay down, try to ignore the pain. The cat flops down on your arm which is acceptable. You seem to be waiting patiently for sunrise, because the doctor and relief and explanation - are the only things that will unlock the door to this room.
