Sunspot that won't go away?

Hey guys!

Along with my floaters, I've now noticed a new anomaly in my right eye. It looks just like a sunspot/afterimage that you get if you look at something bright, but it hasn't gone away in 24 hours. I mostly notice it when I blink. Have you guys ever experienced something like this? Did it go away? I haven't done anything unusual that would have caused it, so I'm a little confused and alarmed.
