The aim of this study is to explore the experiences of hyperbaric oxygen/oxygen therapy for people with Long COVID and/or Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). It is known that many people with ME/CFS and/or Long COVID have tried hyperbaric oxygen/oxygen therapy but there is a lack of formal studies in this area.

​

You are eligible to take part if you have ME/CFS or Long COVID and have tried hyperbaric oxygen / oxygen therapy.
