Hey Rich - I had intraoral surgery on both sides, concurrently, and it was not bad. Worst part for me was that my tongue swelled up from the device they use to hold it out of the way, so I had a hard time breathing and swallowing for 24 hours. Have someone with you in post-op with a pad of paper and pen so you can communicate. The pain was very tolerable after the first 24 hours, but they gave me steroid injections and some searious pain medication overnight because my tongue was so big. Have crushed ice and cold liquid for the first 24 hours. After that, warm liquid - bone broth and coffee with cream kept me going until everything settled down. I could not eat normally for 2 weeks then another week of soft food. I could not drink protein drinks or eat ice cream because they made too much mucus. I was scared, too, after all I had read, but it really was not a bad experience at all. Looks like you have a good surgeon lined up. I was better almost instantly, so it was worth the effort to do it for me.
