Hi Dear, Welcome to HCM. Understanding your concern. As per your query you have symptoms of severe abdominal pain and burning sensation post partial hysterectomy . Well the symptoms you mention in query can occur due to many reasons like food poisoning , food allergy , infection of digestive system , gas , acid reflux , stomach flu or colic . The symptoms can also occur as complication due to hysterectomy . You should take oral rehydration solution as well. I would suggest you to sips of water or other clear fluids on a very frequent basis. You should avoid solid foods for a few hours try small amounts of mild foods such as rice, applesauce and do not take foods or drinks caffeine , carbonated beverages , citrus and dairy products. If condition doesn t get better then consult gastroenterologist for proper examination and get complete examination done. Doctor may prescribe antiemetic drug , antibiotics ,anaspas and antacid . Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
