Bloomin' age again: nothing works quite as well as it used to. Nose cold, but not bothered, except that eyes and nose water, particularly if it's cold, but can also happen when it's hot, whilst walking in the middle of a hot day. The optician thought the eyes might be blepharitis, but having religiously followed directions, eyes are no better, and nose leaks whenever it feels like it, along with the eyes. Basically I understand it could be that the nerves supplying the eyes and sinuses are overactive for no obvious reason. Feet too hot in trainers and too cold in leather shoes, winter or summer. But sandals and socks perfect, as long as I take a hot water bottle/heated wheat bag to bed for my feet. All about managing old age (66!) I guess.
