My right side hurts under my rib cage and into my back, but not on the side. Had test on galbladder came back fine. Had chest pains on left hand side into back and my right arm felt warm. Had chest x-ray, came back fine. Did, however, had two doctors say they heard gurgleing in my lungs thought I had blood clot, but blood test said no. Having problems breathing, had lung function test, came back not perfect said I couldn't get enough oxygen into lungs. Lungs do seem to hurt in the center of my body on the left hand side and at the top of my chest and into my back. Have had acid reflux for years. Some times so bad that I throw up yellow junk. Have it somewhat under control. I am 46, 5'6", 220 pounds. No major problems. Hysterectomy in 1999. Father died of pulmonary fibrosis, nothing else wrong. Mother has high blood pressure.
