Kelly, Angel, this pain is so acute there is no mistaking it... I only had one gallstone, they gave it me to keep (haha) but it was under an inch in length and it was such a nuisance.
There was a saying about being 'fat and forty' years ago, when the majority of people had this problem... I was around that age when I had mine and it was years of unhealthy eating that caused it probably!
Try not to worry love, it's easily sorted and the pain is worse than childbirth, now that takes some beating!
