Thanks everyone - your answers help confirm my guess that PN could be seasonally affected. The variety and range of changes that you all experience due to weather is enlightening. Still learning something new about this aggravating condition every day.

I agree barometric pressure (and humidity) can definitely affect how the body performs - influencing BP and water volumes. I would also guess that maybe in stormy conditions there is extra electrical charge in the air which could have an 'excitability' effect on nerves?

KnowNothingJon - I experienced Florida weather before I had PN - even then the heat & humidity was difficult to deal with - can't imagine trying to cope with PN in that climate. Kudos to you for sticking it out.

I guess this means I need to get my A into G and get stuff done while I can manage before summer arrives.
