Well, the MRI showed some abnormalities, but nothing that would explain Jeremy's current symptoms. This is good news, since it means he doesn't need spinal cord surgery, but it's still frustrating to not know what the problem is. As the neurosurgeon said, "I'm sorry you don't know what the problem is, but at least it's not one of my problems." So, I guess we are back to square not-quite-one, and will go back to the specialist who ordered the MRI and see where she would like to go from here. I'll keep you posted.
