As told in Dr Ritchie Shoemaker's books, I was appalled that CFS doctors would lie to patients by neglecting to tell them toxic mold actually started the famous Chronic Fatigue Syndrome but I was even more surprised when "ME/CFS advocacy" also decided to withhold this information
Patients with mould illness average 7 symptoms across muscles, brain, gut, sinuses and mood.
Doctors see one patient with one of those symptoms and treat it.
Their home environment never comes up.
This is why people stay sick for years.
