Ask away hun lol kidney stones can most of the times pass by themselves, but if they are bigger doctors might use some ultrasound thingy (lol sorry no idea what it is called) it makes bigger stones break and they become smaller and then you pass them later on...i never had them that bad thank god!!! You should really go back to your gp if you still feel so unwell and meds don't help too hun...
Don't want to panic you in any way, but I had similar pains as you describe,... but you can never tell where they are coming from, but if your gp will give you urine test he should see if it is because of kidney stones!
I had mine while me and my FI lived in Denmark for a year...so was quite scared cos thought i might have appendicitis and didn't have gp there as well(luckaly almost everyone speaks english there very well!)...so went to A&E and they sorted me out lol gave me some super duper painkillers and they helped and after about 3 weeks they have done another test and stones were gone, yay!!!
But either way, I think you should also fallow Mel's advice and drink as much fluids as possible in the mean time , cos this way if there is something there it will come out real soon and you will feel much better!!!)xxxx
Take care love and keep us up to date on how you feel and what your gp will say!!!
Really hope you will feel better soon...
