This started to really have me worried. DS1 had to be absent from school for two days, because of some mysterious severe headache started from Saturday. He literally laid in sofa for two days in a row, and at one point looked really pale and barely eating. He had a bucket next to him all the way through day and night in case he'd throw up. Then it mysteriously disappeared after 3 days. He went back to school, started eating normally and did the usual physical activities at school for the rest of the week.
Then last night, he complained a bit at dinner time, saying he probably drank too much swimming pool water in the swimming class on Friday. This morning, he woke up really downbeat and barely had anything for breakfast before he had to lie down on the sofa again not moving. He obviously is not pretending. I have him paracetamol about an hour ago, it doesn't seem to have helped. He asked for a bucket as feeling might vomit. He's been like this for over 2 hours now, just lying in sofa not moving.
I want to thank it's nothing. But it's hard to ignore two weeks in a row a nine years old could feel so poorly for no obvious reason. But then the symptoms are different. It's that kind of situation if he sees a doctor, they would just think I'm overreacting.
Am I being unreasonable???
