Russell, I think a worldwide network of CRPS sufferers would probably be able to put the forecasters out of a job pretty quickly!!
We are having funny weather too, one minute sunshine, the next darkness, hail, heavy rain, cold, wind, the whole shebang. Everything aches today and my feet and back are burning a lot last night and today. Oh to be in a nice stable warm climate without these dramatic highs and lows....
Take care, and hope you feel better soon x
Bram.
