Does anyone else have this uncomfortable sensation? It feels like pockets of air bubbling and popping around the spine. It's not pain like a spasm or cramp, but such a horrible uncomfortable feeling that it makes me queasy. There is no audible noise, clicking or clunking and it happens when I am laying or sitting still. It feels like small amounts of pressure quickly building in one spot that suddenly pops. Diazepam is ineffective and these continuos sensations can last for about an hour before gradually easing up.
