I recently have left lower lobe wedge resection and am positive for b cell-marginal zone lymphoma. Since I've had he surgery, I have had terrible GERD. The surgery was over 2 months ago. I had GERD before the surgery, now it's worse. Was placed on Omeprazole had problems before and then had the same reaction, mastitis. Went on Protonix, since feel like I'm sucking on a battery! The acid is terrible, no caffeine, no alcohol and eating small meals. Propped my head up with pillows at night, still no relief. I am miserable. Have not started immunotherapy or chemotherapy yet. Call GI doctor, have to wait 3-4 weeks to see them. I saw someone take pepto, I just might try that.
