question: I have been experiencing a pretty severe constant pain in my upper abdomin for the last 4 hours. When Im standing it becomes a sharper pain that causes me to walk a bit hunched over. I had tried to go to the bathroom but that doesnt feel like or seem to be the problem nor do I have any nausea sensation. I did just start taking Celexa 3 days ago and melotonin at night for sleeping 2 days ago.Thank you
