GOOD NEWS!!! Today, we had our appointment with Grey's neurosurgeon and his MRI hasn't changed from last year! His doctor explained that the changes in his bladder are most likely due to the bladder maturing and changing. His tethered cord, syrinx, and arnold chiari malformation haven't changed at all!! He was pleased with the progress that Grey is making and we don't need to go back until our next scheduled clinic appointment which is in May!!! God is SO Good!!
