Prayer Needed!

My brother Kenny is hanging in there, but my grandson Robbie is not doing real good. The pain in his head has come back with a vengeance, and his sight is worsening.He has to go to Chicago wednesday for a MRI. My daughter and her ex were told they would get the results of the MRI the same day it is done. With the insurance my grandson has, it takes so long to get an appointment with a specialist, and then the drive to get to one is not easy, as there is none available close by their home.
I am so worried, as this has been going on for a few months, and my grandson has been suffering terribly with the headaches and vision loss.So far, the only diagnoses has been water on the brain and intractable headaches, but there has to be something causing this.
