When ascending in an airplane, I am fine, the entire flight I am fine, and then as soon as we start descending, it feels like someone is poking me in the forehead with a bunch of needles and my head feels like it s about to explode. Holding my forehead and applying consistent pressure alleviates it for a few seconds, but I have to keep doing that or it immediately comes back. I fly a lot for my job and need to know if there is something I can take to feel better or to cope with this pain better.
