Just wan't to know what the following symptoms could be ,gas on and off nau!

You have seemed to have given your own and effective diagnosis.Acute to chronic reflux, but this requires professional investigation, as the stomach acid comes up into your esophagus causing a burning in the throat and the other symptoms that you have already described.The acid from the stomach which is a strong hydrochloric, to which is surprising to some to understand, causes this problem and is extremely distressing if progresses without treatment or investigation.My young daughter suffered this problem and was eventually corrected after investigation and the correct diagnosis, and has since been able to get on with her growing up even though she was still very young.

Seen it and it was treated and corrected.

It does sound like acid reflux to me. I don't understand the headache in all of it but, the gas and the nausea, chest pain are all signs of gas and or. acid reflux. Usually when you have acid reflux you will get a burning in your throat or, your stomach will hurt a lot. I have had terrible acid reflux before and when you lay down to go to sleep it is usually worse because of all the acid coming up will burn your throat and make you nauseous.You can take an OTC medication called Pepcid OTC. I used them and they worked really well. I know that I was given prescription strength Pepcid which is only taking two of the Pepcid instead of taking one. You said"that you haven't eaten anything to cause it" but,it can be caused by something that you ate the other day especially if you had anything that contained citric acid like, an orange or, even drinking a pepsi or some type of caffeine can cause the acids in your stomach to go haywire. If it doesn't go away later on today then, you should consult with your primary care physician.
