<human>: My 11-year old son tells me he has sharp pain in the center of his scrotum. It is intermittent and has had it for the past four days. The scrotum is normal color and he does not think it is swollen. Hurts more when sitting down. No pain during urination. Seems slightly more sore, but not significantly, after running around. Does not recall a recent injury to his scrotum. Has not been very physically active outside of PE.
<bot>: Thanks for asking in Chat Doctor forum IN short: Intermittent torsion can cause this. Explanation: Usually torsion testis occurs in young individuals. Sometimes it may be for a short time called intermittent torsion. SO, only you may not have noticed swelling after that.  Please visit your doctor at the time of pain and ask for Doppler investigation to rule out this. If pain is present now, then visit your doctor now only.
