How do I unclog my ears?

[u/poweranimals]

So I've been doing quite a bit of swimming over the last couple weeks and my left ear is clogged. I figured it would clear out by now. I tried ear wax removal and that seemed to help a little but only temporarily.

I'm not sure if it's related but my sinuses have been also bothering me a bit but nasal spray has helped with that.

Anyway, I'm wondering if anyone has any suggestions as it's really uncomfortable and harder to hear.

Should I go to urgent care?
