Hi there, does anyone have any idea what this could be. I had corn today at noon and 7 hours ago started feeling a bit nauseaus, had some cramps and urgency in going to the toilet, but no diarhea, just normal stool. I thought it was because of what I had eaten, and expected to maybe have diarhea, but it didn't develop in that way. Now I am really nauseaus and I feel like I need to use the bathroom, but whenever I try I cannot have a BM. What can this be? Why does it last so long? I felt several times I was on the brink of vomiting, but it didn't happen. Any idea what medication I could take?
