This is going to be very long so I apologize in advance. Four days ago my 5 year old son began vomiting, it was night time and right afterwards he seemed to feel much better so I sent him to school on Monday, he got sent home the first hour due to vomiting. I took him to his PCP, he said a stomach bug has been going around and that he also had a throat infection as well as being very dehydrated with 80 ketones in his urine sample. He prescribed him 3 days of antibiotics, 4 Zofran tablets, and a weeks worth of Bentyl. Said he could go back to school Wednesday (today) but my son complained he was still sick (though he hadn t vomited in about 18 hours) and very tired (though he had slept 12). I took him back to the doctor after letting him keep sleeping for another 5 hours, he said he was still tired and felt sick, the doctor gave him an antibiotic shot and sent us on our way. He fell asleep about 6 hours later, still exhausted, stomach still hurting but he seemed much better. After a 2 hour nap, he woke up and began vomiting again (after well over 24 hours from the last time he vomited), it started clear as he refuses to eat but after the 4th vomit it began to turn from clear liquid to light grey, then darker grey with grey chunks in it (looking similar to a wet wad of toilet paper) and then it began to turn an almost reddish brown color. Its coming out his nose, its projectile, and im beginning to think it s not just a small stomach bug thats been going around. Any ideas on what it is, and how I can help him feel better? Should I take him to the hospital tonight or just back to the Pcp tomorrow? Im honestly desperate so thank you for taking the tine to look and respond to this!
