Update: Day 3: Woke up this morning to find that right side is again affected. Just to clarify, it feels like my ear hole is being pinched together, although again, it looks perfectly fine and I can hear perfectly fine. After about 3 hours of head being upright, the right ear is almost back to normal again.
Update: The pressure has seemingly lowered a lot in my right ear/jaw, maybe this was something that needed healing over time, so i'll wait another 2 days for the left side to make improvements before I send myself to the doctor.
