Without : Without examining you, it's hard to tell what might be going on. Muscle spasm maybe? This isn't a complaint that is characteristic of any specific disease process. If you are having continued problems with the forehead sensation or with your sinuses, you should see a board certified otolaryngologist in your area for an examination. They may better be able to guide you as to what it may be and how to treat it.

?sinus infection: A sinus infection could cause fluid to build up in the forehead area. Change in cabin pressure could cause uncomfortable sensations in the sinuses. Allergies could also cause the sinuses to fill and produce symptoms like you described. You may require allergy skin tests. See your doctor.
