my son has stomach cramps - center of stomach - no fever. He was nauseated for 2 days vomited the first day  - held food the second but still complains of stomach cramps. Wants to sleep and lay flat - does not want to get up and walk around because of the pain.
HI. The symptoms of vomiting, pain in the abdomen and pain on walking is definitely an indication for investigations:I would advise you the following:Take him to the Pediatric Surgeon to get a physical examination done to get a clinical diagnosis, to be supported by ultrasonography, blood and urine tests and stool tests. It may be due to : -Tummy tonsils-meaning enlargement of the lymph nodes of the abdomen.-Appendicitis- by default this has to be ruled out in every case of pain in -abdomen of a child.-Worms. The best diagnosis is a high resolution ultrasonography. Some blood, urine and stool tests. A therapeutic trial with a course of an antibiotic, metronidazole and probiotics under the guidance of a pediatrician / Surgeon always helps to solve the problem and to get a diagnosis. Also given is a dose of medicines active against worms in intestine. I hope a consultation with a Pediatric Surgeon, investigations and a course of an antibiotic and metronidazole should solve the problem. If this is indicative of appendicitis, please go for the surgery of appendectomy.
