Got back from the doctor's office a short while ago. Had a good, efficient appointment. The news, such as it is:
1. My ears have no wax in them. The doctor is guessing it might be narrow/plugged eustachian tubes, but agreed that as i'm noticing hearing loss I should see an otolaryngologist. I now have a couple referrals to follow up on.
2. My left toenail, simply put, needs to be shimmed. Should be fairly simple with enough soaking.
