If you're just starting to note ear pressure/discomfort, go to an ear/nose/throat specialist as soon as you can. It'll save you much trouble in the end if you have an inner ear infection.

A few years ago, I was starting to note degraded hearing and slight pain, and I ignored it thinking it was just a cold/sinus problem. Few days later the ear drum burst. It felt like someone was shoving an ice pick in my ear repeatedly. I was out for a few months on FMLA until the drum healed, and have had tubes installed ever since to ensure that no more fluid builds up.

Going to an ENT is worth whatever your insurance co-pay is, trust me.
