Welcome,
I didn't have surgery on my tongue but I did have two tonsillectomies (palatine and lingual), two sets of biopsies (BOT and other areas) and two laryngoscopies looking for the primary site (they didn't find it). Between the chunks they took out of my tongue and the sores from treatment, I was a hurtin' pup. I still have some swelling as it takes a long time for those wounds to heal (I'm 6 weeks post treatment today) My speech was compromised a bit and while it has improved greatly, it's still slightly compromised.
I had the last surgery which included a selective neck dissection Feb. 7th so you can see how long it takes for wounds to heal in the mouth. Patience is going to be key in the healing process.
Positive thoughts and prayers
