Please tell me what is causing my to see floaters on the corner of my eye?

Floaters: Sounds as if you have had a posterior vitreous detachment. This is a situation where the vitreous(jelly) of the eye detaches (not a retinal detachment), it then "crumples" up leaving dots, spots, strands of blurry vitreous; i.e. The "floater". When it pills away, it causes flashes. You should have an exam to ensure the incident did not tear the retina, which could lead to a retinal detachment.

Aura: This can also be a sign of migraine if you are also getting headaches. It rarely represents an inflammation inside the eye. See ophthalmologist.
