Through the Looking Glass takes readers through the confusion around what long COVID really is and out the other side where it is possible to have a much clearer view of what treatment will work and why.This practical handbook addresses what long COVID is, why it affects some and not others, and how best to help those who get it to recover. Based on his 30+ years experience of studying neurolymphatics and helping patients recover from ME/CFS and fibromyalgia, Dr Raymond Perrin gives the basics of WHY and HOW to use his highly respected Perrin Technique to underpin recovery from long COVID and restore healthy lymphatic drainage from the brain following COVID-19 infection or vaccination.Bringing together the post-pandemic context, the background science and Dr Perrins clinical findings, this new book is a clear, concise account of the structural and neuro-immunological problems that can lead to the symptoms of long COVID and is ideal for patients wishing to gain an understanding of their complex condition as well as for health practitioners and physical therapists wishing to understand the basics of lymphatic drainage and how to restore it to health with the Perrin Technique.
