I've said all along that some of our "symptoms " may in fact be good and a compensatory response.
Also if my understanding is correct, if we have antibodies to something, our immune system is aware of and working on the problem. If we can get our immune system to start being active and working on the problem things should start to improve. For example, a friend of mine kept getting tested for Lyme. She had all the symptoms. Yet her test was always negative. However, after she started IVIG and got her immune system more in gear her next two test showed positive. She is now being treated for Chronic Lyme and starting to feel better.
Sometimes symptoms that are not pleasant are the better of the evils. Could be our bodies mechanism for trying to correct something worse. Another example, I have HyperPOTS and very high norepinephrine levels with standing. That causes tachycardia and anxiety. But it is my body way of increasing blood flow to my heart and brain. However uncomfortable it is, it is better for me to not suppress it. I tried it and was much worse for it.
