My son is 15 and his joints have ached for 3 years. and they pop on their own. its very uncomfortable for him. what meds will help w/ the discomfort?

A physical exam by : His pediatrician is needed to define the problem ; look for a cause. Joint swelling, tenderness ; overlying redness, point to types of arthritis. "popping" of joints may not be relevant , but some kids with hyper-extensible joints (lax ligaments) experience pain during physical activity. Some people with lax ligaments have a connective tissue disorder. Findings will determine treatment.
