If you were upbeat and chipper yesterday, chances are you have 28 percent less pain today. The opposite holds true, too: If you were down in the dumps yesterday, you may have more pain today. The findings come from a study of 94 adults with rheumatoid arthritis (RA) who kept daily measures of pain and emotions for 30 days. The researchers – two of whom are funded by the Arthritis Foundation – say day-to-day regulation of negative or positive mood is a key variable for understanding how people with RA experience pain and may become an important treatment target.
