It was a bit surprising, then, that beginning in mid-2009 I began to experience frequent ringing in the ears and strange, repetitive lower-GI symptoms.\n\n(2) In 2014 I began experiencing neuropathy in both feet. Shortly thereafter both hands went numb. My feet began to be cold all the time. I consulted my doctor. He suggested Raynaud's Syndrome as a tentative diagnosis.\n\n(3) In 2016 new symptoms began. In addition to ringing in the ears and neuropathy in hands and feet, I had intermittent night sweats, urinary urgency, occasional severe eye pain, intermittent tachycardia, and rapid development of varicosity in the veins of both lower legs.\n\n(4) After researching my strange array of symptoms, I hypothesized that they might be caused by high-frequency sounds emanating from motorized equipment atop a building a few blocks away. I sound-proofed my bedroom. That didn't help. I tried sleeping in a different room on the other side of the house where I seemed to be less symptomatic. That did help, yet I couldn't imagine why.\n\n(5) In 2017 I learned that pulsed microwaves from wireless communications technology can induce some or all of the symptoms I was experiencing. I purchased a meter for measuring RFR as well as one for measuring AC magnetic and electric fields. We switched off our WiFi-enabled Internet router, opting instead for wired-only (Ethernet) connectivity. We shielded a wall in my bedroom where WiFi was coming in from the house next door. \n\n(6) Most of the newer, more concerning symptoms dropped away within a few months after implementing our mitigation measures. No more tachycardia. No more night sweats. No more severe eye problems. No more numbness in my hands—I could sign my name again!\n\n(7) Since 2018 I continue to have varicose veins in my legs. (Once contorted, veins cannot return to normal.) Recent tests reveal I have \"chronic venous insufficiency\" in both legs.\n\n(8) By experimenting with different environments and measuring the levels of RFR that “trigger\" my symptoms, I've discovered that any space, indoor or outdoor, where RFR peaks at more than about 300 microwatts per square meter is unhealthy for me. Lingering for more than about 15 minutes in such a place can cause a feeling of malaise involving fatigue and lower GI discomfort, plus \"brain fog\" and possibly a headache. I also typically experience \"buzzing\" or burning sensations in my lower legs. Essentially, I am now sensitive to all forms of wireless communication technology. I am also triggered by AC magnetic fields emanating from home appliances that have fairly powerful electrical motors (vacuum cleaners, refrigerator, clothes washer).\n\n(9) I discovered a couple of years ago that PG&E installed \"smart\" (RFR-emitting) electricity meters in our neighborhood in January of 2009. Perhaps those are the original inciting stressors.\n\n(10) Our use of WiFi from 2011 to 2017, as well as our neighbor's adoption of WiFi beginning in 2014, may have caused the amplification of my symptoms during those years.\n\nPart Two: Scientific Evidence Regarding Biological Effects and Potential Health Effects\n\nTogether with two colleagues, in 2018 I measured ambient levels of RFR in four residential neighborhoods in Davis, California. Our goal was to find out how much RFR exists and what frequencies are present. The essence of what we learned is this: (i) the level of RFR varies greatly, from a low of just 2 to as much as 20,000 microwatts per square meter, (ii) all neighborhoods are \"saturated\" with RFR from mobile phone base stations (cell towers).\n\nIn 2021 and 2022 I participated in a worldwide RFR-measuring campaign. The results may be viewed at the website GlobalEMF.net. The project revealed that power density of RFR along streets in the downtown areas of many cities exceeds 10,000 or even 100,000 microwatts/m2. \n\nUnfortunately, environmental levels of RFR peaking above about 1,000 microwatts/m2, and especially those peaking above 10,000 microwatts/m2, are associated with biological effects of a neurological, cardiovascular, or neuroendocrine origin.\n\nVarious peer-reviewed papers published since the late 1980s, and especially since about 2000, together reveal that the pathophysiological symptoms are of biochemical and biophysical origin. The mechanism of action involves nitric oxide and peroxynitrite and various complex and interconnected biochemical pathways intrinsic to the human body (and to other forms of life). \n\nI'm uploading a 2007 review paper by Pacher, Beckman, and Liaudet that aids in understanding the breadth of the potential pathophysiological symptoms.
