9/10 Philadelphia Collar – Excellent support for head and natural curve of the neck. It
maintains the head and neck in good relation to each other, aiding CSF passage
through the cranio-cervical junction (between head and neck). I had a gross
reduction of my symptoms from the first day I wore mine, some immediate, some
eventual. Point of note: You do need to wear collar linings with this one!!
Hope this helps, as it might not be the right type of collar that you are using, that’s all,
Thanks for the info. Very helpful. I will look up the Pheladelphia Collar on line and give it a try. I have really been struggling for the last few weeks and I have to do something. The pressure and symptoms are so severe that I am experiencing A LOT of irritability, anger and even rage (which is scary). I have some really sore spots on the back of my head on the right side that radiate pain down my neck and right shoulder if I push on them. Right now they are sore even if I don’t touch them – maybe this is related to the rage.
