How long can CFS last?
The illness varies greatly in its duration. A few recover after a year or two. More often, those who recover are more likely to do so from 3 to 6 years after onset. Others may recover after a decade or more. Yet for some, the illness seems to simply persist. CFS often occurs in cycles. It can be frustrating to obtain some relief, but then not know whether you have recovered or if you are merely between cycles.
