This past Thursday I woke up having terrible pain in my abdomen and went to the ER. Got blood and urine work was done. Also had X-rays of my abdomen. It came back with me just being really constipated. Was put on a laxative. The past couple days I've started to regurgitate after eating or drinking with some burning effects in my throat. The abdominal pain on my left and the right side has gone away but I still have like a burning/itch sensation going on. My stool has been yellow and loose during this time as well. I've also been burping a lot more too. I'm going to stop using the laxative and wanting to either choose Prevacid or Prilosec and not sure which is best.
