Acoustical Trauma or Hyperacusis?

3 weeks ago a coworker dropped a heavy metal stool next to me on the ground. My left ear immediately started aching. The next couple of days I didn’t think anything of it.

But day 3 it got to the point where I would feel vertigo and my ear would ache after hearing sounds/music at a certain volume (just over medium)

It has seemed to have gotten better but I’m at week three and tested medium volume (50-60%) and my ear will start to kind of ache.
