You desperately need to see an ophthalmologist as your description most resembles a retinal detachment that is getting bigger. Left untreated it can cause the entire eye to go blind. If there is a 'safety net" hospital for the poor or indigent with eye services I would head their immediately. You might also discuss with your extended family borrowing money to get it looked at, diagnosed and treated. PLEASE TAKE ACTION, THIS IS NOT SOMETHING YOU CAN HANDLE YOURSELF. YOU NEED TO SEE A EYE MD OPHTHALMOLOGIST.
