I just attended a very convincing presentation of stem cell treatment for peripheral neuropathy. It showed that the symptoms can virtually disappear in a month or so. If its so good, why can't I find anything that the Mayo Clinic is doing? Also, the Mayo website says that 'some medications are possible causes of peripheral neuropathy, but doesn't say which ones! The presentation today said the culprit was statin drugs. I have been taking statins for 20 years or more. Should I stop?
