I’m as sure as I can be this has nothing to do with MS, and pretty confident it’s also completely benign, but it’s so gory and yucky when it happens.
I’ve just been eating - well, gobbling, if I’m honest (it’s chocolate!) a bar of Aero. Nothing hot, hard, or spicy.
Right after I’d finished, I noticed my tongue didn’t feel right. Not painful, but a bobble on the side/underside. Went upstairs to inspect it in the mirror, and found an enormous, scary looking, dark red blood blister - which I washed my hands and popped without difficulty, and then rinsed with oral antiseptic.
I had one exactly the same place, only a few months ago, so it’s beginning to look as if I have some kind of weakness there.
I know I always advise others not to trust Dr. Google, but of course, on both occasions, that’s where I turned, and found that if it’s sudden like that (I definitely didn’t have it when I got up this morning), it’s almost certainly benign, and caused by minor trauma (who the hell could hurt themselves on Aero? It could only be me!)
It has a complicated and scary name: angina bullosa hemorrhagica, but is nothing at all to do with heart angina. Flatteringly described as more common in the middle-aged and elderly.
So now, in addition to everything else, it appears I have to put up with benign gore that especially afflicts the middle-aged and elderly, and, in my case, can be triggered by as little as eating chocolate in a reckless way. I’m positive I did NOT bite my tongue - I’d have known.
