Neck sounds like broken glass

Hi All: I am wondering what exactly causes the neck sounds that sound like glass grinding? I do not have this symptom all of the time and sometimes it involves pain and other times not. It honestly sounds like bone grinding to bone but then after a day (or more) it is gone. If the inflammation was causing this from LD, why would it miraculously disappear as fast as it appears? Anyone experience this neck sound? Thanks~

Thank you Andy. I see there is another post about neck sounds, I did not see that today when I posed mine. I am curious as to why if its Lyme related, it does disappear at times. Yes, it returns but I do have pain free and sound free days which are nice.

Dowa,
In my earlier "what does your neck sound like?" post, "tickledpink" mentioned a similar sound in her/his knees. When Lyme travels to the bigger joints like the knees, it causes arthritis. It could be similar; even though I've never heard of getting arthritis in your neck. But you never know; it is something to think about. I'm not sure if anyone really knows why people who have Lyme also have crackling necks; or the answer would have been posted a hundred times by now.

Yes, I can only say that I have terrible pain in my left foot and funnily enough it is the foot which I badly sprained a few years ago.I also broke two toes on the same foot last year.I guess Lymes is the master of taking advantage of the body's weakest points.
