Brad, I would definitely see the ENT and you'll probably have to get yet another audiogram to really nail down whether you have a conductive loss or not. Conductive losses can often be corrected either surgically or with medication, so it's really worthwhile to find out what's going on.
I had a large conductive loss on my left side due to otosclerosis (growth of extra bone which immobilized the bones in the middle ear). I had surgery for it three weeks ago and can hear on that side now. If your bad ear is fixable, it would be a shame to miss the opportunity. Good luck!

Had stapedotomy on left ear in May, 2015. Prior to that had a severe/profound loss across all frequencies in my left ear.
