Hello Doctor, three week back i has sudden upper abdomen pain and i was rushed to hospital, I was given painkiller injection and som gas medicine. I was asked to do sonography and i was diagonse with two gallstone with 5 mm each. Again after three week i had same attack but i felt it was milder than the previous stil i rush to hospital becouse of scare. Doc give me to optionn operate or control on food. i am just afraid is this pain was because of gallstone or any side effect of letroz medicine 5 mg which i was taking from my day 2 to day day 7. Please suggest. I want to plan my pregnany and it getting delay day by day because not able to find exact cause of the pain. thanks in advance
