See Your Doctor: !6 yr old "hard, swollen veins rt leg". In your age group, these symptoms point to an anomaly of the blood vessels to the right leg which could interfere with normal circulation. These can be present from birth and go undiagnosed until some time later. The main anomoly may lie deep while causing the superficial findings that you can see. See your doctor now for correct diagnosis and treatment.
