I think things have changed a bit . my first was about 13- 15 years ago . that one sucked hard compared to this last one . major swelling , major black/bruising , major burning in the nut-sack , numbness for months if I remember right . I didnt lift at the time , and I didnt listen to Doc's advice about diet either .......which didnt make things any better . fuckin' constipated for a week . fiber is your friend......your ONLY friend .
