Electromagnetic waves and indirect effect: Don't you believe anything which isn't visible?

One day, a patient came my dental clinic to cure her knee pain because there is a close relationship between the biting conditions and knee conditions. I thought that her knee trouble was related to her biting condition. Therefore, I asked her to remove her denture. While her denture was removed, I adjusted it near her. While I was adjusting it, the patient reported that her knee pain had disappeared. I was very surprised because her denture was not placed in her mouth. Next, I moved her denture away from her. The pain in her knee recurred. I did not understand why such a result occurred. Howe ver, I have seen similar results time after time in my clinical work. When a substance was brought close to a subject, the effect of that substance on the subject's body increased. When the substance was moved away from the subject, the effect decreased. When the subject was shield from the substance with aluminum foil, the effect of the substance also decreased. As a result, I imagined that something like electromagnetic waves was being emitted by the substances and that these 'waves' were influencing the physical condition of my patients.
