I am at my wits end.. I am a bundle of nerves and anxiety. My 4 year old son woke up last Wednesday at 5:30 am throwing up. This went on every twenty minutes until about 12 pm, so 6 1/2 hours of vomiting and laying around. I got worried because the day before he had fallen and bumped his forehead on our ceramic tile, me being the over worrier that I am, took him to the doctor because I was worried about a concussion. He threw up three times during his exam. Dr. said he looked very unwell and wanted him admitted for iv fluids, observation, and a head CT. We get to the hospital and of course he stopped throwing up. His head CT was normal and they watched him over night and he did good. Only throwing up once during the night. They released us Thursday afternoon and they were convinced that this was just a stomach virus that needed to run its course. Here is where it get weird. He is throwing up every night only... Around 1-2 am. He does not vomit during the day. He has only had diarrhea twice on Saturday. He is wanting to lay around a lot and sleep a lot. He will play for maybe two hours a day and then say "Im tired" and lay down. He is not eating. He is drinking. He munches on dry cereal through the day. The weird part is at night he wakes up saying "im not comfy... im not comfy..." he flails around alot. Anywho... today is Tuesday of the next week, so today is day 7 of whatever this is. Im at my wits end. Anyone ever experience something like this for this long? Why only vomit once at night??? They keep saying they have seen viruses do this before.. but I HAVENT. We took him back today and they want to get a stool sample (per my request).
