Hello There Glojer,
Personally I feel worse in the Summer time. Even though I don't get out much at this time, when I do I feel that the heat not just the sun makes me very achey and so on. I do tend to have a lot of swelling in my legs, ankles and fingers, not just my joints.
I find that in Winter because of perhaps wrapping up well and keeping our hands and legs and body generally covered and warm, this then stops the tendency to hold ourselves stiff and tense, which I find does contribute in developing these aches and pains in our bodies because of the cold.
Just how I feel. I hope you are doing ok, love as always to your wonderful husband and yourself.
