Hmmm? Could it be? Maybe not....

My stomach has been killing me at night time, can't lay on it :( without feeling as if something is pushing on my sides. I have major heart burn when I eat something that has a spicey kick to it. Also get a feeling of something like a butterfly had ran across my stomach lol. I took a PT 3 months ago and got a positive reading, but took another expensive kind and it was negative. Any know of what could be going on?
