It is pretty common knowledge the FDA is in Big Pharma's pocket. It is more profitable for Pharmaceutical companies and the economy in general to not have a cure, but prolong the illness. I firmly beleive that government is holding everyone back from these things. Access to stemcells for research were put on hold by George W. when he was in office, now just starting to be released by Obama. South Korean's supposedly discovered cure for cancer a couple years ago and this information just disappeared after a short stint. This is all a result of Capitalism at its worst and maybe something that goes a little deeper. There are plenty of homeopathic and herbal/supplemental remedies that are very effective for PN. We are all taught to beleive that conventional medicine and pharmaceuticals are the best, healthiest and only effective way of dealing with our condition. This is flat out not the case.
