Hello I had an X-ray last month after going to hospital with heart racing due to hyper thyroid and the X-ray they said was fine (they were looking for a blood clot) 3 weeks later I get told at my endocrinology appointment that they saw an area of hazy opacity in my upper lung and I’ve to get a ct this week. I’m a non smoker for 20 years otherwise healthy,, I’m quite worried x
