Have name changed. 6 months ago I was diagnosed with a large (7cm) ovarian cyst. It's due to be removed via surgery in the Autumn. I don't know if it's connected but In the last few weeks I've started to experience severe nausea. I also get diarrhea at least 2 or 3 times a week. I'm struggling to eat anything resembling a normal meal. Sometimes the nausea goes for a short time (a day or occasionally two or a time) and I can eat normally. Today has been really bad. I managed a small bowl of cereal about 9am. I now have a sandwich in front of me but have only managed one bite. My periods (usually regular) are all over the place (two in one month or none for ages). I've tried taking antacid tablets but they're no longer working. Wibu to go back to the GP or is there anything over the counter I can take to stop the nausea?
