For over a month now I have been suffering from stomach pain, nausea, a bit of gas and bloating, and food tasting really weird/gross. I've been taking prescribed antacids for it and lots of generic tums. A similar thing like this occurred a month ago, however, my stomach only hurt when I touched the very lower portion of it then. Today my stomach hurts when I touch it mostly in the middle and when I don't touch it. The pain feels like the inside of my stomach is just raw. I don't have constipation, diarrhea, or vomiting occuring, but I am having problems sexually. I've taken urine and blood tests all coming back negative. The blood tests were to check my blood counts etc., whether I had an infection, and to check my organs. I'm not pregnant as well. Does anyone have an idea as to what it is and what it is from?
