Good afternoon. I've been seeing some very slight shadows/outlines beside objects since 3 days ago and I'm very worried about it. My vision has always been perfect and I've done a brain scan 5 months ago (for other reasons), and it was normal. But since this weird vision symptom started, I've been worrying if it can be caused by some serious problem in the brain. Is it possible that, though I have a recent brain scan with normal results, this vision problem can be caused by some serious brain problem? I've been to a neurologist yesterday, and she said that this vision problem couldn't be caused by any serious brain condition because in 5 months a serious thing wouldn't develop enough to make me have vision symptoms like this. She said I didn't need to do another brain scan. But I'm still worried about being a brain tumor that could have developed in 5 months that's causing these slight shadows, because they are still very slight, so I'm worried the shadows could be not so bad yet because the problem could be in the beginning. I have severe anxiety and my neurologist said I should blame these vision symptoms on it, but I'm still very worried, as these shadows/outlines are scary. You think I should do another brain scan? Or is my neurologist right? Thank you.
