So obviously I know that this isn’t the solution, but would a hole in the head equalize the pressure and relieve pain? Or are pressure headaches within the bloodstream or something internal?
Really wish I had a tire valve on the back of my neck to balance out.
Short answer, probably not. Anatomy is complex, and the source of the pressure may or may not be at the single point where you most feel it. Even if it is a single point, you wouldn’t be dealing with what caused the pressure, and the body would seal the wound as quickly as it can.
