I go to Dr Google, too but sometimes he can be scary so I end up going to the clinic to calm my nerves.
When I was losing my vision, Dr Google said it could be a stroke or a list of other things. I was also scared that I was going blind, I only have one eye that works, it turned out to be cataracts they fixed my good eye and now I see fine.

Google is good to go to but you need to follow up with a real doctor.
