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.
No idea unfortunately, but definitely not to release pressure. You don’t get air in your brain, it’s all fluid. Outside of the hospital, all the drains drain to somewhere internal, usually the abdominal cavity
