Sounds like a migraine beginning. Does a terrible headache follow ever?
Hi....what do these spots look like? Are they dark and move around a lot? These may just be what are called "floaters", we all get them, they're normal to have and you can see them better against a light background. Sometimes they appear round but often they appear oddly shaped. The more we look for them the more we notice them. What I get with migraines is my vision starts to break-up until I can't see anything but zig-zagging colors and it only lasts about 20 minutes. You can get the physical part of a migraine without the pain, that's what I have. My vision acts weird but I don't get the headache. Talk to your parents about seeing the doctor about this, don't be scared they can help you.
Sounds like migraine to me. Iget the same. My migraines started when I was 17. Don't think it is anything worse than that.
I also have floaters in one of my eyes where little pieces of black float around. Again nothing sinister.
I get the zig zags and flashing lights like mammo, but I get the migraine headache too with pins and needles and numbess in face and limbs.
See your doctor. I don't think it sounds like anxiety.
