Yes I have experienced something like that last week. I was vomiting, (Which I have done rather frequently for the last few months but that is another matter.) all of a sudden I got a cramp in the front of my neck on the left side. It lasted only about 30 secs., but I almost had to 'pop' this area in the front before it would stop cramping!! This happened 2 more times, once while I leaned over the tub to wash my hair and the other when I stretched my head back over the back of the couch. I still can't turn my head to the right without some cramping pain. (I already have deg neck problems that this added to my misery

.)I go to my ENT tomorrow and will ask him what could it be. I've asked my physical therapist and massage therapist and the have never heard of such a thing, they only came up with a muscle spasm perhaps but never heard of it popping like I had happen!!!
