Possibly: Many things can cause arm weakness and radiating pain, including nerve pain. However, at your young age, i would suspect shoulder instability which can ultimately lead to rotator cuff tearing. If you have had persistent difficulty, make an appointment with your doctor to help get to the correct diagnosis before undertaking a treatment plan.
