i suffered really intense panic attacks for a couple of years to which i was eventually hospitilised for. I was constantly burping and bringing up wind and the threads above are completely right. Because we take on so much air when we are panicking or anxious this makes us bring up wind. It really is very common and normal. i currently have discomfort in my left rib and pain in my left thigh and right arm. have totally convinced myself its lung cancer (i am a smoker) ive managed to find all my symptoms in every lung cancer site ive been to. yep i know shouldnt google. although i dont have the common symptoms like cough, coughing up blood or breathlesness
