I'm panicking instead of enjoying my weekend. Yesterday evening before going to sleep, I was using my phone, when I noticed that it's difficult to read, because the middle of my vision was a blind spot. I turned the light on and the strangest things happened. The blind spot was growing and moving around, then I was seeing a colorful (red and blue) line above the center of my vision. Soon after, the whole left side of my vision looked like a heat wave which was moving rapidly, here's a really accurate depiction - https://en.m.wikipedia.org/wiki/File...ng_scotoma.gif
After about 15 minutes my vision came back to normal and I started googling. As you can see in the link above, I think that it was a scintillating scotoma, which is an aura that happens before migraines. The thing is, I had no headache after, and I never suffered from migraines. I'm panicking about a brain tumor, because I've read that such aura without a headache before age 40 warrants neuroimaging, and I'm 26. I'm going to a wedding today but I'm literally shaking in my bed right now, what do I do?
