Left Ear Tinnitus Gone?

So about 4 days ago I took a quick nap and woke up to my right ear sounding louder than usual and feeling very plugged. Keep in mind both my ears have been plugged ever since I've had tinnitus.

However, my left ear wasn't very plugged I realized. After a bit I realized the loud tinnitus I used to experience was only in one ear rather than both.

This may or may not have to do something with a head injury. I was skateboarding and smacked the left side of my head against concrete pretty hard, it surprised me because as soon as I hit my head my tinnitus spiked so loud I thought it would be like that forever.

It subsided and now I'm left like this. To be honest it's more annoying than before, it feels weird with only my right ear plugged and ringing loud vs. my left ear.
