Yes it helped more than CCSVI
I've had back pain after my cat got paralyzed(Probably polio) around march 2013, the pain never went away in the back for weeks. It got so bad, i researched, on the computer, why the pain in the back was getting worse. I found about Klenner and VItamen C. and I took massive quanitities orally about 3-4 grams per day. The back pain went away, the weakness in moving objects also dissipated.
Klenner was right, i believe injections of Vitamen C would have cured my cat also. My wife did not allow me to inject her with vitamen C. it is a crying shame she did that.
