I constantly hear this high pitched rining

I have this sometimes.

Most likely tinnitus, which isn't curable. Still, there are other possibilties and you need to get a second opinion.

Low magnesium levels?

Sometimes I'll notice it while I'm it's really quiet. I think it's normal for me because I've had it forever.

im hearin that noise right now.. except its from my tv.. i her it all the time

You have aids

Most people have it. Also this can be a symptom of stress and anxiety which will make it worse. If it's fairly loud and you are younger, it could be stress and anxiety causing it.

Allergies can also cause it. If you are laying on one side, fluid can drain down your inner ear and create the ringing.

Most people have tinnitus to some degress. All the cars, the music, etc. The human ear wasn't built for that.

Tinnitus. I got it myself. I have severely damaged ear's. Get a new doctor.

What's a rining? Is that like a rhino?

See another doctor.

Ya that makes sence me and my dad operate heavy machinery since I was like 13 and I'm constantly exposed to unbearably loud noises

Tinnitus. It is caused by repeated exposure to unsafe noise levels. My Great-grandfather was a famous gunfighter; his nickname was "Ringin' Randy".

No, see another Dr...its obvious you must have an inner ear issue of some sort.
