I just went through a lasting attack, 3 plus hours or so. I will have to try the Apple Cider Vinegar next time. What helped me tonight was a hot bath. My pain was pretty high when I got home from work, I could not get any relief from anything so I ran a hot bath and laid in there for about a half hour. The pain wasn't completely gone in the bath but it provided so much relief and that made me more comfortable.
