I've just started experiencing this problem.
About a month ago I woke up with heartburn that lasted for a week. Nothing I did helped but it went away.
2 days ago I woke up with heartburn again but now I'm experiencing pain in my stomach when I swallow. It doesn't matter what I eat. I have to stretch when I'm swallowing so the discomfort is not as bad. I noticed I have to belch also.
Help what is going on? Any info on this would be very welcomed.
