I have had the same thing in the neck area and around the throat and chin. I think mine is mostly spasms in the muscles when they get irritated or catch on the cervical ribs I have. Its annoying and sometimes painful. Mostly to get it to stop a little stretching or a muscle relaxer. Strange thing is my cervical ribs are floaters which means they aren't actually conected to the spine...weird as it sounds...I've seen the x-rays..and they catch in the muscles in the neck and create the spasms...sometimes I get the swallowing problems and it feels like I'm being poked in the throat. So I know the feeling, may not be the same anatomy and physically as everyone else, but I know the feeling.
Also been getting extreme pain in the chest and right above the breast area...more sore muscles.
Hope this advice helps. At least I don't feel weird, knowing I am not the only one getting it.
