I am hurting so bad in my stomach at times, and I know it s not an ulcer I had that before and know the symptoms. this is very different.. I m thinking it s a hernia, but the pains moves all under my chest, sota like something is sliding around and it is very painful at times.. I am having an appointment with an (Can t Spell) that will stick some kind of light down my esophagus to see what it is.. my question is , can they tell from doing this? the pain is gettin worse everyday..
