Hello. I am traveling in Cambodia and 5 days ago started to have intense stomach pains. I vomited for the first 4 days non stop. No diarrhea. The stomach pains continued to get worse. Yesterday I went to a Clinic in Cambodia, there the dr did a ultrasound on my abdomen and then diagnosed me with gastritis. He prescribed me Nexium, Phagel susp., and Debridat. It was very difficult to communicate with him, he did not speak english very well. That was 24 hours ago. Since then the pain has gotten even worse. The stomach is incredibly twisted and painful and pain is spreading to my back. The medical services in Cambodia are known for not being that great and I m wondering if this issue is more serious than the dr. s diagnoses. Or if you agree to think that it is simply gastritis, is there anything you can recommend that I take to ease the pain? Please let me know what you think, Thanks,
