Hi Sara, I went through quite a few different cervical collars, and while some were HUGELY helpful, others made me feel much worse. I am guessing that some collars work against our individual anatomy. I don’t know of an easy way to find out what may help except by trial and error. What I’ve found is that if the collar helps, it is usually indicative of high ICP. Because you may also have CSF rhinorrhea (that leak from your nose), you may benefit from Diamox to reduce your pressure. Diamox allowed me to stop using a cervical collar (after 2 years of use!). Everyone one is different, of course, but I wonder if you have tried it yet? So glad you’ve joined us! Gentle hugs…
