For what it is worth, about six months ago I was struck with an excruciating, throbbing pain in the left leg. I went to an urgent care center and it was diagnosed as "peripheral diagnosis." I was told that it may or may not go away, that if it did, it could come back, that it was difficult to determine the reason for it, and that anything they might give me may or may not help. 800mg doses of ibuprofen and vicodin failed to do much. I also tried muscle relaxers, which also did not work, but expected if it was truly a nerve issue. The only thing that helped was heat. I was skeptical, but desparate, and ordered this product. I have been taking it since. Since the onset of the neuropathy, after about ten days the pain in the left leg started to subside and eventually went away. However, I was left with numbness in the leg, but that is also pretty much gone. However, about the time the pain in the left leg went away, I got pain in the right leg. However, it was "different" and did respond to ibuprofen. I thought that perhaps I had tweaked it compensating for the left leg when it was in pain. In the meantime, I saw my primary care physician who seemed convinced it was something to do with either my hips or lower spine. Various tests and numerous x-rays revealed nothing. I should also note that I was treated for prostate cancer (hormone suppressants and radiation), ending over a year before this began. My oncologist does not believe that the radiation was the cause, but I have talked with others that did have nerve issues following radiation. I do not know. About a month and a half ago, suddenly my right leg (that still had the residual "different" pain) went through exactly the same cycle as the left (starting with the throbbing, excruciating pain), but it was a bit less severe. Again, the pain eventually went away entirely, but leaving some numbness. Now all pain is gone from both legs, as well as the numbness for the most part. Did the Neuropathy Support Formula help? Who knows, but I am unwilling to dismiss it. I have, however, recently reduced the dosage by half (2 capsules/day instead of 4). So far so good.
