Very true! I had multiple infections in my heart from a failed root canal. I had to have the tooth removed and a cavitation cleaned out before I stopped passing out when I got around various smells. Then I did some zapping with a frequency generator.
I went to an acupuncturist that has what sounds similar to one of Hulda Clark 's diagnosing machines. He finds frequencies for specific pathogens and bacteria, etc and you kill them with the frequecy generator.
MCS appears to be different with each person. My guess is that where ever your body is weak that is where the bad guys set up housekeeping. That is why doing one specific thing will not "cure" MCS. The remedy is different for everybody.
What I have left is convulsions when I get around bad smells. It looks and feels very strange. I don't know anyone else out there that has this symptom with MCS.
