Hi welcome to Health care magic forum. You have got your gallbladder
removed 3 years back, now after 3 years you have got severe stomach pain, motions, vomitings, and shoulder pain
.It has nothing to do with the gall bladder
removal. It appears to be some food poisoning
, resulted by contaminated food. It needs treatment by a doctor. I advise you to consult a physician for diagnosis and treatment of pain, vomiting and motions.
Besides i advise you to follow some diet recommendations as avoid taking more of spices, chillies, junk foods, oily foods, pulses, sprouts, fish, meat, chicken, sea foods,to avoid gastric irritation.
Take more of green leafy vegetables, milk egg, fruits juices, and dry fruits which improve blood, general health, resistance , to such infections, and stamina to withstand such conditions. Wishing for a quick recovery and thanks for calling.
