Quite often people think they should be able to do particular activities, such as housework, gardening, home maintenance or sitting at a computer, and push themselves to do things, despite it causing significant increases in their pain. This in turn, may cause a “flare-up” for one or several days, requiring them to “lie low” and rest a lot more and avoid even more activities. This leads to frustration and gradually less and less tolerance to certain activities. This is called the “Boom and Bust” cycle. We see it very frequently!
