Well I have been on Nexium for 2 weeks and most of the symptons have subsided. I have seen a ENT and a Gastro DR.. The gastro dr. suggests an endoscopy, which I will schedule for Oct.. He wants to make sure there is no damage. I have had such great support on the boards, that I have another question. Besides fear of the endoscopy, I have had an itchy, burning tongue toward the back of the throat. I also wake up with a bit of a sore throat. The sore throat seems to get a bit better after rising. It feels as if flem or drainage is in the back of my throat. I also have noticed my stool is green. Is this side effects of nexium? Should I contact my doctor or is this normal?
