Reports reproducible headaches near a mobile hotspot, improvement with distance or switching it off, and …

Hello, Please look into mobile hotspots and headaches. I work remotely and when I do so from a car, coffee shop, airport or where have you with my hot spot on I get a headache within 1 minute. When I work without Hotspot, no headache. Its repeatable and consistent for the past 5 years. I do notice however when I place the mobile Hotspot more than 6 feet from me the headaches are gone or much more subtle. When the Hotspot is turned off, my headache resolves within minutes. Perhaps its rare or some people are more sensitive than others, but this is a real issue for me and makes me concerned what the health effects are. I dont suffer from headaches otherwise and am in great health. I've taken into consideration confounders like posture, stress, poor sleep, long sessions but the issue remains. I've even had my friend "blind test" me by turning a hotspot on and off near me without telling me and I was able to tell every time. Thanks!
