I got news for all you people complaining about symptoms like fatigue, vision disturbances, balance impairment, stiff neck, muscle weakness, cold hands and feet, low body temperature, fever, sleep apnea, swollen lymphnodes, constipation/diarrhea, brain fog, sinus congestion, dry mucous membranes throughout the body, hair loss, dry skin, rashes, acne, etc. etc. -these are most likely caused by neurological damage!
There are well-known viruses that causes this state of illness like Enterovirus, Coxsackie viruses, ECHO viruses, Polioviruses and maybe others...
Google f.ex. "Enterovirus" or "non-paralytic polio" and be suprised.
PS! I just had a CSAPx2 stool sample analysis which showed NO parasitic or yeast infection in me, but elevated levels of secretory IgA supporting the theory of a virus-infection!
