Symptom Saturday: ME/CFS symptoms explored

Symptom Saturday is ME Research UK’s ongoing series dedicated to exploring core and additional symptoms of ME/CFS one by one, helping to further understanding of this profoundly debilitating disease. Each symptom is explored over two weeks, covering relevant research, clinical guidelines, lived experiences, and management strategies, and including key comorbidities. To help others understand the everyday realities of ME/CFS, we also run a survey for each symptom and share the profound insights gleaned.

You can keep up to date with the series by keeping an eye on this page.

Surveys

ME Research UK wants to present its work and the realities of ME/CFS in ways that are relatable to supporters. The lived experiences of those affected convey the reality of the disease in the most direct way possible. We are collecting anonymous quotes from individuals with confirmed or suspected ME/CFS about various symptoms to be used at our discretion online, in print, and for internal organisational education.

Each survey will stay open for an extended period for those who want to participate but can’t at present.
