Hi, Abdominal pain can be due to 2 reasons gall bladder stones and gastric ulcer. In this case your gall bladder is already removed so most of time it is due to gastric ulcer. For now, consult gastroenterologist get endoscopy done. Use abdomen for any recurrent stones. Sometimes stones can be lodged in gall bladder passage. For this you need to go with ERCP as last resort. For now, take low spicy food, plenty of water. Tab Pantoprazole 40mg early morning before breakfast. Spy sucralfate 10 ml trice a day. Follow this medication for 2 weeks and go with other investigations. Take care. Hope I have answered your question. Let me know if I can assist you further.
