I am more sensitive with hands and feet getting cold, and that can be a major distraction and performance issue in me feeling my feet. But heat is bothersome too. I try to stay in shade as much as possible during the summer, as I don’t seem to sweat to help release the internal heat. Getting in the swimming pool helps. I avoid hot showers and saunas. My water must be lukewarm, so I let my dishes soak awhile in hot water before I immerse my hands in the sink to wash them. It was extreme when my PN started 7 years ago, but once getting to the right dosage of Gabapentin for me, the extreme temperature sensations lessened in intensity and duration.
