question: I have discomfort on right side of my body along with a sensation of heaviness. It started in my right side under my lower rib. I have had ultrasound ct scan both negative. this discomfort, which I describe as burning pressure, has now spread to my right shoulder down to my lower leg, that whole side of my body feels what I also describe as solid, like muscle tightness all the way down and up. My right lung feels tight and I have trouble taking breaths when exercising and laying on my back
