I have been having stomach pain since Feb. The pain usually comes on suddenly and gradually gets unbearable over time. The pain stays in the center of my stomach between my ribs. Once the pain gets unbearable then comes the nausea and vomiting. The pain has gone from being almost every day to every 3 days to now every week. I have lost over 40 pounds dealing with this and the doctors I talk to don't know what's wrong. I have been put on acid reflux medication and a lot of other medicine that don't work. I have had my gallbladder taken out in January and I am still having these same symptoms.
