I don’t think we can ever reassure ourselves 100% with this kind of situation (or any, come to that). I also understand the fact that the x-ray was unnecessary must make you feel worse, but of course the doctors didn’t know that at the time.
One of my children had several chest x-rays at the age of four and I was very unhappy about that. He is now almost thirty and seems to have suffered no ill-effects.
Reading will never satisfy you, we always find a piece of information to alarm us further. It’s hard being a parent with OCD, we will always over estimate the dangers our children face. We can never protect them totally, and if we did, what kind of existence would they have? I can recall how I agonized over vaccinations, convinced my children would be the ones who would suffer adverse reactions.
Please don’t feel badly that you might come across as having ‘an issue with any reassurance’. That’s the nature of OCD and an analytical mind. We might feel a degree of comfort, but we then see another possibility, another worry. We desperately want to be reassured, but many around us may believe we actually deliberately ignore reassurance and delve deeper. As if any sane person (and we are very sane) would torture themselves in this way deliberately!
Best wishes, Tricia.
P.S. I recall the days when children had their feet x-rayed whenever their parents went to buy them shoes. I know this practise has stopped, but I used the machines many times. At the age of 17 I was working with an x-ray machine with no protection. I was often actually in the rays' direct line. I have to admit I obsessed about that for many years!
