My wife's been complaining about the same thing, she went to the doctor, next is x-rays and a chiropractor, she thinks pinched nerve but hard to tell without x-rays.
My wife turned the heat on tonight, said it was too cold this morning, pretty early to turn it on, I think its usually in the middle of October average wise.
I remember getting a frozen ass sitting on those aluminum benches back in the 70's. Went to a game in December after a foot of snow fell and they didn't clear the snow, just brushed it off the benches, coldest I've ever been I think and I've camped out in below zero weather. At least I had a fire camping.
When I went fishing in June in New York the deckhand bought a new truck last year. He was offered 10g more than he paid from the dealer, he declined because he knew he couldn't replace it.
