"A cold is a good thing, I think, because we have not been sick while we have had this parasite. We also have not had any allergies (my allergies have been severe all of my life and now I don't have any at all), and joint pain has decreased. These are the good symptoms with this parasite."
this is interesting because i very rarely caught colds these last 5 years or so even though my health has been deteriorating. i suspect you are right. sometimes i think my immune system is too weak to produce a fever or fight infection.
