<s>[INST] My 11 year old son recently has been complaining of feeling his stomach is turning, headaches, dizziness, and then his nose bleeds. He never does throw up but will complain like he feels his is about to then suddenly he feels dizzy, the headache comes and then most of the time but not always his nose will bleed. This is not normal for him so I am concerned. Any thoughts?
