The commenter reports severe migraines during prolonged occupational cordless-phone use, improvement afte…

Dear Officials, I am writing to submit my personal testimony regarding the adverse health effects I have experienced, which I believe are closely associated with prolonged radiofrequency (RF) radiation exposure and urban electromagnetic field (EMF) environments. Part 1: Occupational Exposure and Neurological Symptoms For approximately 5 years, I worked in a medical office where my duties required me to hold a cordless phone to my ear for 3 to 6 hours a day, 5 days a week. Due to strict patient privacy regulations, I could not use the speakerphone function. During this period, I began suffering from severe, debilitating migraines, occurring 1 to 2 times per month. The pain consistently originated from the area just above my right ear and irradiated across the trigeminal, orbital, temporomandibular, and cervical regions. The pain felt as though it emanated from either the area above the ear or from the top-central part of my head. It was strictly unilateral (affecting only the right side). These episodes were accompanied by intense "electric shock" sensations that spread across my entire cervical fascia, lasting for about 4 days. During these crises, the pain caused severe gastric distress, making it impossible to eat or move. Relief was only achieved by lying in a completely dark and silent room, pressing the affected eye against a warm pillow. Mild massages or heat applied to the top of my head provided slight, a temporary light comfort. In terms of medical management, paracetamol offered minor relief only after 5 to 6 hours, without resolving the electric shock sensations. Conversely, a non-steroidal anti-inflammatory drug (NSAID), specifically nimesulide, consistently alleviated the pain and the electric shocks within 20 to 30 minutes. Part 2: Cessation of Exposure and Symptom Resolution After approximately 7 years, I left that employment, which completely terminated my daily, prolonged use of the telephone. While I maintain a mobile phone, I strictly avoid placing it near my head. I rarely make calls, and when necessary, I use a tubeless airtube headset or utilize the speakerphone function, keeping the device at a distance of at least 50 to 60 centimeters. Within 12 months of terminating that occupation and changing my wireless habits, the severe migraines began to subside significantly. I do not take other medications, I do not smoke, and I maintain a very balanced, healthy diet and a calm lifestyle. Through careful observation, I have ruled out other potential lifestyle or medical variables. Part 3: Environmental Sensitivity and Urban Re-exposure Over the past 15 years, I have observed a consistent, repeating pattern regarding my environment. Every August, I reside in a secluded coastal and mountainous area characterized by a very low density of routers, low vehicular traffic, GPS tracker, and low population density. In this environment, my physical health completely regenerates, and I experience high levels of physical energy. However, upon returning to the large city where I currently reside, I experience an immediate and severe physical decline from the very first day. The sensation is described as a persistent, distressing "burning" feeling in the brain, accompanied by a constant state of neurological tension, alert, and over-stimulation that prevents any real rest. This systemic stress causes gastric burning and profound fatigue, rendering me unable to perform simple daily tasks. Upon my return to the city this year, I suffered a continuous 9-day migraine crisis. My systematic observations over fifteen years confirm that a isolated, low-EMF environment restores my health, whereas the high-density urban environment consistently causes exhaustion and severe pain. I urge federal health and communications agencies to thoroughly investigate the biological mechanisms underlying these exposure patterns, to acknowledge the reality of environmental sensitivities, and to implement protective standards, particularly regarding long-term occupational exposure and CEM/radiation density. Sincerely.
