I am having back pain. Also , there are certain symptom like whenever I am eating something , I am feeling like as if it is going slowly and many a time I need to drink water so that I get relief from the pain it cause in my back and when I get burp , due to that burp I feel pain in my back. When I sleep straight , I get pain again in my back but when I am standing or sitting , I get the pain only after the burp.
