It was a long time ago. When you go to the hospital for a check-up is went well, but when I go to the X-ray. Must take off and removed to the brace on the X-ray. The doctor said to take a deep breath and steady.I heard that runs thought the doctor to see the function of the lungs when we ran ran hard on X-ray machine. The doctor thinks electric shot? Why don't you still told again that deep breath and steady.I want to book the land away.
