I'm sorry i do know it's awfull,it's just been a lot of years for me.
Have you had a thyroid or a test for diabetes,have you asked your
question to your family Dr. The problem with PN,if that's what you have
is there something like 200 kinds..
Please will you keep posting,there so many kind and good people at
neuroTalk. This is a slow day,but you never know you may get many
answers very soon.. Many Blessings
