Re: Light burning behind sternum
This is a typical symptom of AR/GERD. In my case the pain you describe as burning (I describe as Gnawing) can occur anywhere between the Bellybutton and the Sternum. I was also given PPIs but never took them as they can become addictive (my own choice).
Instead I just take Gaviscon and try to stay with a Healthy diet.
So!.. The answer to your question is Yes it is a typical symptom along with many other ones. Solofelix.
