@njgeorge Hey George, it's me....NJEd. I did not notice your original post. I see that you have received lots of good information from fellow PNer's. What caught by attention was the "Thanks brother" response....I said wait a minute, that sounds familiar. You are on the right track, getting as much info as possible. Knowledge about your PN as I mentioned before is the key. You may not find out the why as many of us experience but any avail treatment plans, supplements could help. Contact me when you have time. Ed
