For people with conditions like fibromyalgia, the chronic pain doesn’t end when you lay down to go to sleep. In fact, the pain often makes it incredibly difficult to fall asleep at all, a phenomenon known as “painsomnia.” Like most forms of chronic pain, the effects of painsomnia are invisible, so when you struggle to go about your day after a sleepless night, those around likely don’t understand how exhausted you actually are.
