Tinnitus.

Wednesday night, my left ear started ringing. It got better, but I woke up this morning with it ringing again.

I recently hurt my ear with a cotton swab. Could the ringing be related to that?

What do I do?

Hi Jordan, see the doctor. You might have pushed wax up against your eardrum which dulls your hearing a little and can cause you to hear tinnitus.

The ringing in my ears isn't as loud or high-pitched today as it was yesterday.

I've been using hydrogen peroxide to clean out my ear. 

I've been able to sleep and hear just fine.
