Interesting that Mike T... I have ankylosing spondilytis and really feel the cold, even now that it is warm! I am also suffering with a wound that doesn't heal and keeps being re-infected (waiting for another op on it) do you think this contributes to the fact that last night, as I was leaving work, I was feeling decidedly unwell? I had jeans on and t-shirt and woollen jacket/fleece type top but had to go under the duvet fully clothed when I got home, just to get warm... it was 25 degrees outside and 22.5 inside.
