My 10- year old just developed issues with blurry vision, seeing in colors and inability to read words and numbers. Some neurologists thought is was migraines and recommended Motrin for headache pain but he has no continuous headache pain. It's been 4 days and his vision is still blurry and comes in and out. He sees words jumbled and numbers jumbled and can't read. He was in a high level in reading and in math and this came on all of a sudden. He has had GI issues for the last 3 months as well. We are seeing an opthamologist and getting an MRI. What could it be?
