I did not have a flap done but I was biting my tongue a bunch when it was still a bit swollen and I thought it was because it was laying funny and part of it was sort of landing between my teeth and getting bit. But now the swelling is pretty much gone and that doesn't happen. If I talk a whole lot, I feel like my tongue is swelling up and it feels uncomfortable. Probably need to give it more time to see how the swelling goes down. Glad the surgery went well. Denise
