Why does my hip, knee and, shoulder sometimes ache? i am only a teenager and i work out regularly, i do gymnastics and cheerleading!

Injuries 4 athletes: Gymnastics and cheer are definitely active sports that you will find yourself at risk for injury. Are the pains occurring at the same time? Have you ever had a hot red swollen joint? Do you ever get a fever associated with the pain? There is a good chance that these are all related to sports and simply will require resting to heal. See your pediatrician for an evaluation!
