What is considered a dose of either that sucessfuly decreases pain. My regular neurologist put me on neuron 300 mg three times a day and when I had no decernible results changed me to Lyrica 50 mg three times a day which is what I am on now for the third day...dont see/feel any improvement. I really question how much this neurologist knows about PN but will see a PN specialist in October. I have been calling frequently and hoping for a cancellation as things are getting worse.
