Ow, my eye.

I'm getting intermitent and partial cloudy vision in one eye, can someone here at least give me a rough idea what's wrong before I go for a ridiculously expensive diagnosis with a doctor?

oh god, you have retinal cancer. My uncle had it. The eye gets puffy and if left untreated would eventually start leaking, everything goes to shit then. That is, assuming you don't die first. Go get it checked the fuck out now.
