It has not happened to me but from what i have read of other peoples posts you may very well be on the road to healing. People who have gotten better have described having symptoms similiar to earlier stages of their PN and some say the symptoms have come in reverse to the progression they had of PN. Keep up the good work. And if you continue to improve or not post here and let us know how you are doing. Not many people have had it for 30 years that post.
