Hi I am a 16 year-old guy and today while in school I got a sharp pain from lower right abdomen to my right testicle and the pain persisted for about 2 hours and kept on getting worse until when I had gym last period I was in a lot of pain when I was walking or running but after running around for a while in gym it started to hurt less and less and then just stopped. What was it? I felt like it hurt real bad if I touched my abdomen or my testicle and it got to the point were I could not sit with my legs together or the pain was excruciating.
