The neurologist called tonight because she had gotten the message that I called yesterday and sounded "distressed". She pulled Austin's MRI, and it is completely CLEAR!! What a huge relief!
So now we can just keep on with the plan of meds for a few years, watching him carefully, and following him with blood work and tests as necessary.
I'm so relieved, and glad to not have to wait all week for these results! Hopefully, we'll get the ultrasound results tomorrow or Thursday!
