Hello Abdominal cramps may be caused by a benign cause like intestinal gases or a viral gastroenteritis or it s a sign of a more serious condition like food poisoning or appendicitis. For now you need to have rest, eat a warm meal like soup or drink warm water and put on some clothes to warm yourself For nausea you can take metoclopramide 3 times daily 15 minutes before meals. I don t recommend taking anti-spasmodic for now to avoid masking the real cause by anti-spasmodic. If your symptoms getting worse, you should go to the emergency department immediately. Hope I answered your question Wish you a speedy recovery Best regards Dr. Noor Farid
