I have stuffy ears or ear pressure? I think?

For a couple of months I have been having this weird feeling in my ear. I don't if its ringing but it feels like me ears are pressured and need to pop. I tried everything. I clean out my ears with Q-tips but its not even really waxy. I tried blowing my nose and holding my breath but it doesnt pop. Do you know what this actually might be? I actually think I started having this after going on an airplane in July. What are some ways to make some relief? I really need help
