Question: Have you ever heard of chiari malformation ?

Emma Markham answered on 12 Jun 2019:

I did not know about this! I have just looked it up and it seems to be where the brain enters the spinal canal, either because the skull is the wrong shape or because the brain is too big for the skill. In many instances people do not know they have this and often no treatment is needed.
