Online symptom checkers are the digital version of the DIY doctor. Plug in what’s ailing you — headache, stomach pains, weird skin rash — and you get a list of what’s (likely) causing the problem.
The key word is ‘likely.’ Depending on which version you use, that list could be spot on, or it could lead you astray — luring you into a false sense of reassurance that nothing is wrong, or sending you into a spiral of anxiety about a serious, and possibly even fatal, condition.
