Testicle discomfort: Your question did not come through completely. Please get checked by your doctor. It MAY be simple strain but if it is a torsion of the testicle that is a medical emergency. You age was not given. Young guys often wonder if everything is ok in that dept. and it usually is but you need to get checked. Peace and good health.
