Hi. Chilly has nothing to do with the testicular pains. While passing #s there might have need a straining albeit less, this has strained the musculature of the abdominal musculature , which in turn can pull up the testes and cause rotation on the way-up causing such type of pain. Avoid any strenuous activity and consult a Urologist as soon as possible. Get ultrasonography and color doppler studies and you may need a surgery if the Urologists feels so.
