Hi Dr. Passi! I have a question,My husband has been suffering from double vision, terrible headaches, floaters, dizziness, and out of body experiences (where he feels that things aren't real around him) for five years. He has seen many doctors and eye doctors and everyone says they don't know what to tell him and that his eyes are perfect and there's nothing wrong with them! He is 25 years old and other than all these things, his health is great! He did do major drugs when he was younger, so I don't know if it's from that or what? He has been doing drugs for the past 3 years to cover all that up and now he's been clean for a month and it's all coming back!!...and he just wants answers! Should he see a neurologist? and what kind of tests should be taken?? Thanks,Sara
