Dani,
I feel strange sensations daily in my tongue & my surgery was 7 mos ago. Some days I cannot do coffee or anything even remotely hot and others it doesn't bother me. The last week or so I have felt swelling & my tongue feels tight, I just continue on, knowing I am getting checked out as your mom is. Dont worry and reassure her as best you can ... I even feel better about the "pulling" sensation in my tongue now I have read YOUR post....Thanks!
Take care
Maria
