Hello,
Yes unfortunately it is normal with this procedure. I have been doing so much research and that is definietly one of the problems. My mom can't swallow anything....it feels to her like its lodged in her throat/chest. It has been 5 months and she still feels the same. They said her esophagus does not need to be stretched but yet in the same breathe that something seems to be blocking the food/liquid from going down. It takes a good 5 to 10 minutes sometimes. She has dropped to 99 pounds and might eventually have to go on a feeding tube at night. Liquids are even worse for her believe it or not. I hope it helps that at least you know a lot of people are going through this. Its just sad that there is not much doctors could do about it.
