I had 4 episodes of attack (heavy pain in middle of the chest and right side of the chest that radiates to the back). I have gallstones (confirmed through ultrasound). 3/4 attacks happened around evening/night (4 hours after dinner) . But I don t have tenderness /pain when I touch the gall bladder area. 1 week after my recent attack , I m having stabbing pain in the left side of my chest. I also have nausea, loss of appetite, diarrhea, joint pain in the leg area, dull body pain, headache and fatigue. Are my symptoms due to gallstones or is there any possibility of IBS/gastritis ?
