Thank you everyone for the well wishes.
Kathy, I read your grass in the nose story earlier when I searched for sneezing on YT. Although the doc looked in Max's nose, I got out a pen flashlight to look again to see if the sneezing may have moved something.
I do think the sneezing changed something because Max exercised his voice a couple times in the last hour and didn't do any head bobbing/hard swallowing afterwards. He also hit a higher note and didn't sound quite as raspy.
