((Notz)) - sorry to hear you're not feeling well and had so much pain. I remember my SIL when she had the attacks - they were excriciating for her. I think you should go for a check up with your doctor - maybe there's some medication he/she can give you and you need to be diagnosed.
Here's an informative website that gives natural remedies to try and you should use a heating pad next time - this calms down the contractions. Try fresh lemon squeezed in water - this also works wonders with heartburn. I've struggled with heartburn for years and never thought lemon juice would work. I figured if lemon is sour, it will makes it worse but it relieved it. I hope you feel better soon.
