Really Need Variety of Input - PLEASE

OK - I started zapping about 5 to 7 days ago - please note that I did have severe joint and leg pain in my right leg and really bad lower back pain PRIOR to using the zapper.

However, since zapping every night - 10=10=20 off three times a night - I have had the most awful symptoms - severe aching all over my body - the worst flu like symptoms ever - then, my already bad right leg is so bad now that I cannot move, walk, stand up - just horrible.

In a few words I have all but become a cripple with unbelievable pain. The original severe pain while zapping was just under my rib cage - such excruciating pain that when I tried to bend over I literally cried out in pain. Now, it has sort of lessened - I did not do any zapping tonight.

What are your thoughts please - ANY AND ALL WHO HAVE BEEN USING ZAPPERS PLEASE GIVE YOUR INPUT. I AM HESITATING TO USE THIS AGAIN.
