For me (diabetic neuropathy), IT'S ALL ABOUT THE WEATHER. And stress!!

If it's going to rain, I'm a dead duck. If the humidity is 90, I'm a dead duck!!!

If it rains, I'm a dead duck.

But if the sun is shining, and there's no humidity, and it's warm as heck outside, I'm not a dead duck and while everybody is dropping dead outside from the heat, and pouring water over their heads, I'm walking just fine and smiling.

But when my son calls (oh boy, do they burn).

So stress and weather does it for me.
