Thanks for taking the time to read my situation.
My almost-4 year old son, Avery, threw up 2 nights ago out of nowhere. He hasn't shown signs of sickness prior to, and was fine afterwards. Then, last night, he threw up a second time. (Serious throwing up... quite a bit and forceful.) Afterwards, he was completely fine. (Even ate.)
Then, this morning, he threw up a 3rd time. He now has 8 red spots (that resemble mosquito bites) on his upper back and 3 similar spots on the left side of his neck. There is a bite (his younger brother) around the spots on his upper back.
He complains of some stomach pain, which makes sense, but does not have a fever. The throwing up lasts roughly 30 seconds, and, afterwards, he's completely fine.
I'm concerned. Does anyone have an idea of what this might be? Thank you VERY much for your time.
