You souldnt live with any pain, every pain has some cause. Your pain sounds to me more like gynaecologic disorder. Especially if no gallbladder
disorder or stones have been seen on US. If analgetics help hen your problem can be muscular or neurogenic so there wont be any intraabdominal pathology. If it persist then complete gastroent. workup must be done including gastrosocpy and colonoscopy
. Wish you good health.
