You have to stop and consider this - would the health professionals allow you to have these scans if they thought that you had had too many for your body to deal with?

Your scan for your appendix was a life saving scan - so it was necessary!

Your dental xrays are normal.

As indeed are the xrays on your ankle & chiropractor.

Listen, the thing to bear in mind is if you are constantly seeking reassurance about your health, then you are more likely to find yourself having tests including scans etc that will increase the number you have in a lifetime over, say, a non anxious healthy accident free individual - that is just the way it is ................................

I think that you are absolutely fine and need not worry - and when you look back in say 10 years time, you may well smile and say "well I haven't had any scans in ages"
