I am not sure....I am actually feeling okay although I noticed tonight that I had that fizzy feeling in both my feet while at dinner.... I'm not sure that the heat affects me....
I am on the fence too...my hands get really arthritic in the cold, but my legs get super wonky in the heat.
I voted "maybe" because for me, I feel like it is any change in weather that can stir up my symptoms. I have heat intolerance, so that of course gets worse in the summer. But when it gets cold, my joints hurt more. Just like any change from my routine can cause a worsening, so can any dramatic change in the weather.
