I am 45 and have hypermobile ehlers danlos. For the past 2 days I have woken feeling like I have a hangover and have developed inescapable head and neck pain leading to nausea and vomiting by the evening. It s not a migraine, I also get them and they re very different. It feels like something has moved out of place in my neck just below my skull. I can get some relief by floating in the bath, but as soon as I sit up the pain returns.
