I have had x-rays on my lungs many times as I have asthma and I have had pneumonia several times. I cracked a rib once coughing. I broke my wrist once. I have had mammy o grams not sure on spelling. And when I was 12 I had some medical issues that required x-rays when they put dye in your veins (if you are familiar with that procedure) any way I have had x-rays many times.
