I am going to see a Spine Specialist and have them check me for Facet Joint Syndrome and AS. I poated a previous comment and many have responded back with great information. Does anyone have major back pain when you lie down in bed. My Lower Back burns so bad when I lie down in Bed which makes it so hard to lie down or even turn over in Bed. When I get up from Bed it's even worse. My back locks into a spasm hunched over until I am able to get back to normal but the pain is Bad. If you have been diagnoses with this AS or Facet Joint Syndrome. Or have these types of symptoms please explain how you feel. All your replies have been Great. Thanks All for giving me a new light on my condition.
