Hi! Good evening. I am Dr Shareef answering your query. This could be a ovulation pain which might occur in between the periods with such severity at times. If I were her doctor, after a clinical abdominal examination I would advise her for an ultrasound of abdomen to rule out any pelvic pathology causing such pain. Otherwise simple anti inflammtory drug along with a proton pump inhibitor would suffice during such pains. 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. I wish you an early recovery. Dr Shareef.
