pressure for 3weeks

im 26, and ive had a pressure in my head in the front, through the temples around my nose and in my forehead, now its just pressure not pain and sometimes when i pop my ears it feels better briefly. i know this sounds like a sinus infection but i have no snot or drainage and i can breathe completely fine through my nose so i dont know what it is. i was sick 2 weeks ago and had antibiotics and felt better, ive had really bad sinus infections in the past one of which clogged Eustachian tubes and gave me a nasty case of vertigo. but currently the pressure is never constant, coming on maybe once every hour or so and lasting maybe 10-45mins and again it just feels like brain pressure.

ill also note that i am a pretty healthy individual with normal BP and physically active with no health conditions that im aware of.

any input would be extremely helpful and put me at ease because i had a dream the other night that i had a brain tumor that was causing the pressure in my head lol (im aware that's most likely not the case)
