Ear popping and pressure (mostly around temples) along with mild headaches (usually later in the day) and occasional pain at the top of my head.

Sounds like: You may have some sinus inflammation and complicating eustachian tube dysfunction. You may want to consider a trial of Neti Pot use (as in saline irrigation for the sinuses) and safe steam exposure to see if things will open up. Otherwise a more formal HealthTap Prime consultation will allow for better guidance. As always if your symptoms worsen, see your doc in person.
