There is only circumstance where my love of all things hot stops short: fevers. When rheumatoid arthritis first began its assault on me a couple of years ago, one of my most persistent symptoms was feeling flushed and feverish. I remember reading about this after my diagnosis, and the fatigue and fevers were often described as ‘feelings of malaise.’ This fancy description always evoked romantic images of old movies where the ingénue lays on her chaise lounge, suffering valiantly from some vague but pitiful ...
