Hello, I am a 22 year-old male (weight 73kg, height 167cms). I've been feeling quite tired for the last few months and only a couple of days ago and on three occasions I've felt this clammy cold sensation, anxiety and I started sweating slightly, especially on the arms and face; it was very scary because for a moment I really thought I was going to pass out or something. I also felt a bit nauseous. I've also had this abdominal pain for some months now: it starts a couple of hours after I've eaten, and the more hours pass, the worse it gets; it's almost always right below my breastbone but sometimes I also feel it in my lower abdomen. I already took omeprazol, milk of magnesia and antihelmintics for that last symptom but didn't get any better.
What is wrong with me? I'm really scared.
Thank you.
