I’m sorry to say there are many ENTs who are ignorant about ES or downplay it because, “It’s so rare you couldn’t possibly have it.” That comment is made even to patients who have obvious ES symptoms AND their CT scans show elongated styloid processes. I’m hoping for your sake that the ENT you see has at least heard of ES & is open to investigating it further if (s)he doesn’t have much knowledge about it. You can also look through our research paper section to see if you can find any that mention your symptoms then print them & take them to your appointment.
Here’s a post by our other moderator @Jules with extensive information about ES symptoms. You’d be welcome to print that & take it with you as well:
