I know exactly how you feel. I could get a job as a weather predictor. Ha ha
My RSD (Four years now) really flares up when rainy or cold weather is on the way. Then during a rain or snow storm, forget it! This monster I live with also does a number on my emotional state too.
Now it's spreading into my leg and already is being complicated by my degenerative cerebral atrophy so I'm in a wheelchair a lot because my balance is effected. Luckily my neurologist knew of this possibility and prescribed one.
I guess all we can do is learn and do our best to live with it.
Best of luck to you...
