Pumping

When i pump i had a sore back,can that be from pumping,what fills your ball sack,lack of something in my body because of pumping that caused my sore back

I would attribute poor posture to a sore back while/after pumping than the act of pumping itself. ;> Fully lay back or sit *upright* in a cozy position while doing it - or get up and pace about. Hunched over, watching your junk? Pops a disc or two out on me too. ;>
