Pressing Near Ear Causes a Rumbling Sound

If I gently press on my cheek below my left ear, or slightly in front of, or behind the bottom of my ear, I hear a rumbling sound in that ear. It only happens on the left side.

This ear also gets a "crick" sound right after I hear a loud sound. That ear also makes a garbled, crackly sound if I'm in the car listening to music, and a certain higher pitches happen.

I was reading online about this possibly being due to C1 and C2 vertebrae being misaligned? (That it's TTTS, but with likely origins in spine misalignment.)

Wondering about this, as I saw a chiropractor once maybe 5 to 7 years ago, and they said I had nerve damage in the neck (based on data they got from a handheld device they held up to my neck and back). I never went back, as they hurt my lower back badly, and I'm not sure how I feel about chiropractors in general.
