Here's my 2 cents worth. From what I have experienced & lived with, the stress is my biggest concern. For me, any stress makes everything worse-I can feel my whole body go numb/tingling. But, what job out there isn't stressful? Catch 22...
I now live in the hottest part of the U.S., Arizona, you can live in warmer parts & take advantage of that a/c. Actually, I cannot handle cooler weather at all now, this has just happened over last year or so. I am hyper-sensitive to cold on my feet & avoid cold at all cost.
Best of luck!
