Hi, apart from your swollen tongue, I hope you are doing ok.         Back in January I had a tumour lasered from under my tongue.    My speech was my main concern,  but after about two weeks it settled down.      Mine was front and side so its like being tongue tied, it took a bit getting used to but the only difference in speech is my 's' sounds are different, but only slightly and to be honest I'm really pleased.                         Before my op. my surgeon said only family and friends would notice a difference, and he was right, strangers wouldn't know.      

Take care.  Colin.
