Hi ola!
Welcome to our forum. ES symptoms can include neck & shoulder muscle tightness & pain because the spinal accessory nerve is one of the nerve often irritated by elongated styloids. Your speech problem is being caused by the vagus nerve. We’ve had a number of members who have either lost their voices or struggled w/ pain when speaking. The vagus nerve also controls breathing, heart rate, blood pressure & gastrointestinal activity among other things. I had blood pressure & heart symptoms from ES, The tongue is also often affected by ES because the glossopharyngeal & hypoglossal nerves can be irritated w/ the glossopharyngeal nerve being the more common problem. I had the feeling of tremendous pressure at the base of my tongue as one of my symptoms & that feeling was gone when I awoke from my second surgery. The other three cranial nerves which can be impacted by ES are the trigeminal, facial & vestibulocochlear nerves.
You’ll get some good information from the link below. Jules has written a number of explanatory posts that start w/ “ES Information” so you can search those two words & the list of her posts will come up for you.
