Hi & welcome!
I agree with the others that your styloids are long & look pretty pointy so could well be causing symptoms… I can’t see clearly enough if there’s any compression of the blood vessels on the images though, but your symptoms certainly sound like they could be vascular. With IJV compression you typically get light headedness/ off balance feelings, head & ear pressure, brain fog, pulsatile tinnitus, muffled hearing like you’re under water. Carotid artery compression can cause dizziness, headaches, TIA/ stroke like symptoms, fainting. So potentially you could have both. The vagus nerve is in the carotid sheath with the IJV and ICA so commonly gets compressed too, & that can cause anxiety, BP spikes, cardiac arrythmias, breathing issues, digestive issues. In addition, as you’ve noticed & @Isaiah_40_31 has said, your hyoid is unusual and chunky, so this could be adding to the mix, as if the processes are long sometimes they can irritate the carotid sinus, which can cause arrythmias too. So lots of possibilities, but I do think it would be wise for you to see one of the vascular doctors - Dr Costantino in NY, Dr Cognetti in PA, Dr Hepworth in CO, Dr Lui in NJ, or Dr Nakaji in AZ. Given that your hyoid bone might be an issue you could possibly see Dr Cognetti as he also looks at this?
I also noticed that there seems to be some other calcification under your hyoid bone where the thyroid cartilage would be, but it looks different to what we normally see in some images, but in the 3rd image you posted it looks abnormally thick, this can sometimes cause symptoms…
Your neck looks pretty straight too, we see this quite often, it’s known as military neck. Restoring the body’s normal curve can sometimes improve symptoms a bit, there’s info on this & exercises to do in this discussion:

So plenty of food for thought!
