I've experienced them several times myself and couldn't agree with you more. Nothing like seeing a grown man curled up in the fetal position rocking back and forth for several days. Hope you pass them soon.
My father had them all his adult life, and he was a big construction type, I can recall him laid up like a baby doing the rocking thing, also crying like a baby. I knew it was miserably for him to behave like that. The removal technique was: 1) pass them naturally. 2)pull them out with forceps, then many years later the sonic tub process came along and cut the mass down to passable.
