I often crumble to the floor in pain from my back shifting letting the bones pinch against the nerves. My MRI's show severe stenosis but I'm having a hard time explaining to the Dr how I can go from okay manageable pain to excruciatingly debilitating pain in one slight move. How do I get the Dr to understand. Another Dr said "classic DDD. Can't help you." Sometimes I think that I should go to the ER when it happens in hopes that they do an MRI right away and it shows the pinching......any thoughts?
