Hi... new to this site and it's great. I have had PN for over 20yrs and really had give up all hope for relief except for Capzasin at night. Then... I read about Valerian Root. (standardized) I had taken it for years for a calmative at night but tried it during the day for the burning pain... IT WORKED. calmed the tingling right down. I now take it PRN during the day and also got the tea, one bag mixed in with my green tea... I also just started taking Benfothiamine/ ALA in cap form. A vitamin B... fat soluble. and now have hopes for relief and some healing of the nerves... time will tell
