He's 13yo and has been complaining of it for two weeks.
It started when he was sick just once in the morning and he had that day off school but since then he says he feels fine and has been going about his business as usual until the early evening when he says he's so tired he's going to bed.
He's already in bed with lights out now, it was 6:15 when he went up on Sunday eve!
There are no electronic gadgets in his bedroom and his phone stays downstairs at night so it's not that he's going to bed to play with those. He gets up in the mornings without any bother.
I'm worried but he's not really "ill". Would you take him to the doctors?
