“My son's joints ache. What should I do?”

I recommend he gets evaluated by his PCP. You may give him some ibuprofen,
acetominophen, heat or ice packs as needed for pain relief.

Kids can have joint pain from a lot of different causes including hypermobility syndrome ("double-jointed") that often a good physical and occupational therapist can treat effectively. If your son has any visible joint swelling for more than 2-3 days continuously, then you should take him to see his pediatrician and ask about getting a referral to a good pediatric rheumatologist.

Pain medicine should be given to him as the Dr. ordered. Warm baths help. Not to hot.
