I’m so sorry that you’re struggling like this & have been dismissed by doctors…
I had a look at your images; we’re not medical professionals here, only people who’ve learnt a bit along the way. And I’m rubbish with tech so I’m afraid I can’t label the images for you, but looking at them it looks like you have a short styloid process each side, but a long calcification beside it, so I’m wondering if it’s actually the stylomandibular ligament, although it doesn’t seem to come from the styloid process, it seems to be from beside it, it’s very strange? Here’s an image showing the stylomandibular ligament :
But obviously there is some calcification there which shouldn’t be, and could be causing symptoms- it sounds as if you’re getting vagus nerve irritation symptoms, here a link to a good discussion by @GrnyAny about this:

It will be interesting to see what one of the experienced doctors says, Dr Hepworth would be good to see if you can get on his list. The Mayo clinic don’t seem to be very aware of ES so I wouldn’t worry about seeing anyone there. I hope that you’re able to get some treatment soon, not good if you’re not able to eat properly…
