Just now, on the phone, I had the biopsy result of the tongue 'lump' excised three weeks ago. I was told it had become a semi-permanent inflamed swelling through a 'Trauma'.
This can mean a bite (but I would have known about biting my tongue THAT hard!) or friction by a denture. Well, I have a two-teeth denture on that side. Must see about changing it.
So, all's well.
