I don't know how I'm going to bring it up... maybe i should just come right out and say hey... by the way.. can you have a look because i have this problem (hopefully i will have my diagnosis by then) can you make sure she isn't affected by this? They have to sedate her for it because it will take 20 minutes and he said if she moves the slightest bit, it will mess up the whole test. That doesn't thrill me, but as the years go by, her feet and ankles get worse instead of better. But if they can see the nerves in her spine, then they've got to be able to see something that shouldn't be there in someone who has a parasite or other foreign thing in their body... but some people DO have them than an mri failed to detect. I am absolutely going to ask though. I don't think its over the top to worry about your child.
