HHS-OASH-2026-0397-0837 https://www.regulations.gov/comment/HHS-OASH-2026-0397-0837 Since around July of this year, I have been experiencing vibrations in my head every night while sleeping. It is a faint vibration that seems to travel from the pillow to the back of my head. My wife, who sleeps next to me, has also experienced this.
