I'm female, 52. Idiopathic PN since 2005. Last year I had new flares all over my body. My breast had a burning pains for severals weeks and also some other new pains. I asked my neuro if it had any connection to menapause. His answer was that during menapause, things become worse in almost every illness. He doesn't know why. I think the right answer is that our hormones are not as the used to be. The cycle is not working anymore - so it might influence many things in our body, including methabolism and many other things - and all these - influence our neuropathy.
Try to relax, do yoga and meditation. it helps a lot.
I found pilates as one of the things that help me.
