I feel? or hear? The same thing. Like clunk clunk. Best way I can describe it. I also have fibro Wackers. I thought I was crazy!! Have been looking for years trying to find someone who knows what I am talking about
. Mine happens when I move my head left to right and is more on my head than neck though. I also have degenerative joint and disc disease, Lupus Sle, Connective Tissue Disease and on and on. I have had a disc replaced with a cadaver bone and bracket in neck. This happened before and after though. I also have a spinal chord stimulator in my back. Dont think any of that is causing it. At least I know there is someone else who has been feeling or hearing it too!
