"for nerve pain/damage, this is better than narcotics and tramadol.  for almost any other kind of pain it does little but i suggest you try it if you have any kind of spinal problem.  i apparently have some kind of lesion or scarring after a badly herniated l5/s1, experience zaps and soreness in my low back and legs, and take 900mg/day three times a day and it is a miracle that this medication performs as well as it does.  great stuff."
