Here's a little history on my stomach issues. My stomach has always hurt mostly every day for as long as I can remember. I get nauseous daily and feel sick. I've been to the doctors and they've run a ton of tests and said nothing's wrong. Fast forward to a couple of weeks ago. I went on a trip with my boyfriend. I hadn't gotten my period (still haven't gotten it) for a month and we tested negative for pregnancy. Middle of our trip, I randomly get terrible gas built up in my stomach that makes me cripple to the ground. Then frequent runny bowel movements the next couple days, sore stomach, skin hot. Then a few days later I felt so nauseous but a head nauseous. Like when you ride a spinny carnival ride. It would not go away. Next day it was gone. Now it has been about 6 days since the first incident and I get constipated for two days then pass a bowel movement, two more days nothing then pass a bowel movement, etc. my stomach hurts every day but it's different than how it usually does. It feels like whatever I eat is not something I should eat and my stomach feels uneasy. Then it doesn't feel like it digests and get acid reflux in my throat. At first I thought it might have just been travelers sickness but it's not getting better and I think missing my period has to do with this. Does this sound like IBS to anyone? Or something different?
