Hi honey,
You def sound like you have gallstones!. I had them 9 years ago and Bekimo sums it up quite well. Mine fell into my pancreas and nearly killed me.
I have two children and I would give birth a thousand more times than to have that again.
The diet can also have brought them to a head. Usually after years of bad eating and then having so much cd ss can aggrivate them.
What ever you do do not make yourself sick as it makes it worse! Although it relieves the pain for a while it inflames the tubes giving you more pain. Try anti inflam tablets to calm it down.
Luckily I had my gallbladder removed through a very lovely hospital who booked me in staight after any inflamation settled down but there are plenty of ways to get it sorted but what ever you do do not let your doctor fob you off.
Good luck and I hope you feel better soon.
