I had my gallbladder removed in March of 2007. I did pretty well for awhile but for the last 3 months I have been having terrible heartburn, middle to right back pain below my shoulderblade, weight gain, nausea, headache and feeling of fullness. I have been taking over the counter acid reducers as soon as I get out of bed as I wake up with heartburn and I usually have to take an other pill sometime in late afternoon/night. Does anyone know what causes this?
