Welcome to Healing Well! Your last sentence is the one that tells the whole story. You don't have to have reflux at exactly the same time as pain. The damage done by reflux can create problems that remain after it subsides.
Have you been to a GI doctor about your problem? If not, it sounds like it's time to go. You should not ignore pain like that without pursuing medical attention.
When you have reflux (especially, reflux that is bad enough to allow food to migrate to your mouth) you should elevate the head of your bed. You can use bed risers or blocks to elevate the whole head of the bed. If you use pillows, you can end up squeezing your stomach and making your reflux worse. Here is a link that provides some information regarding dealing with reflux:
Here's another source:
This site says to lift the bed to put the risers under, but actually you should first take the mattresses off. Also, I've found that it's fine to leave the wheels on...especially if you buy the commercial bed risers. Generally they have an indentation at the top that hold the wheels fine. Also, if you want to raise the bed further, 4X6 boards sawed into pieces can be stacked under the bed risers to the level you're trying to achieve.
Again, glad you've joined us.
