Joint pains . Your son is suffering from multiple joint pains. He needs to be evaluated by his pediatrician or a rheumatologist for proper diagnosis, work up & treatment. It is good he is active but be careful, may be he is overdoing it with all these activities, that might aggravate his joint pains, do it in moderation. I hope he feels better soon. .
