I would say (for me) that seasons have a huge impact on PN. I have PN as well as severe autonomic neuropathy (a subset of PN) and summer is always harder on me for the the autonomic symptoms because I am completely heat intolerant. That being said, my regular PN seems worse in the winter as I don't tolerate the cold either and my feet and hands have increased pain during cold months. So basically, I have problems in both seasons, but for different reasons. I think my best season is spring (and my favorite) when temps start to warm up and neither of my conditions are suffering greatly because there are no extremes in temps...and I also have several fun things to do (like getting my veggie garden going), so I have things to take my mind off any symptoms.
