I can't say whether that is all PN but it is possible. If you had a chiropractic adjustment that seemed to cause symptoms, hopefully that will settle down as your body adjusts. If you are feeling a lot of stress, that can definitely cause worsening of symptoms. Look into breathing exercises, meditation, guided imagery, & Yoga. These really help. These types of things will also increases circulation in your extremities, which we all need. We had a psychologist come to our PN meeting once and demonstrate that meditation increases the temperature on the skin on our hands.
