University was this:

Patient comes in, you listen to them, you do some tests, you give them treatments and then you’ve fixed them.

Real life is this:

Patient comes in, they talk about things in a way that you can’t understand (e.g. “it burns behind my knees all the time, except when I’m doing something), you do a barrage of tests and hope something comes back which will help you with a diagnosis.  Most of the time you can’t diagnose anything.  You try some treatments and then another and then another and then hopefully something will work.

Real life is messy.

But that’s real life.  You can wish for it to not be messy.  But it is, and always will be.
