Hi ! Good afternoon. I am Dr shareef answering your query. Any pain on the right side of lower abdomen is not necessarily an attack of appendicitis. If I were your doctor, I would advise you to stop eating from out side if you do and also would advise you for a stool test. If positive for a any ova or cyst, treat them with appropriate drug. As your CT and barium meal are normal, appendicitis could be ruled out for the present. However, appendicitis is usually a clinical diagnosis and so you should get yourself examined whenever you get the pain in that particular area. There is no way of preventing an attack of appendicitis. You should take the fear of a general anaesthesia out of your mind, as now a days there is a lot of recent developments in this field, and the anaesthesiologist is equipped with more training and more sophisticated equipment to bring the patient out of anaesthsia. So stay care free. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing health care magic to clear doubts on your health problems. Wishing you an early recovery. Dr Shareef.
