Adrian is bang on target! My MRI was really easy, just relax and let the machine do it's thing, the technician will look after you.
I looked at my scan and it really didn't mean much to me, the radiologist pointed out the areas he thought needed further investigation and I had a biopsy.
That came back negative so all is well.
I managed not to get too tied up in the things that are posted online. As Adrian has said before, a lot of it is negative because the ones who get a good result don't tend to hang around to post.
Please just try to clear your mind down of the horror stories and only start to worry WHEN there is something to worry about.
Enjoy Christmas and new year like there's nothing wrong with you, there probably isn't.
When you get the all clear you will feel pretty much you wasted a lot of energy worrying for nothing.
Best wishes, mick.
