¿Left eye pain and ligthflashes, brain tumor?

[Kassje]

Hello, i need help, for more than 1 year i´m suffering with a really annoying eye pain in my left eye. I went to the ophthalmologist 3 o 4 times in a month, beause the pain was really hard to overcome, the problem is since two years ago i have been seeing floaters  in my vision range, and when i´m reading i see ligths in my vision but the ligths are not in the front, are in the top of the page or the white page. (the especialist doesn´t found something strange my eyes are normal). Rigth now i can´t go to the doctor, and i need help idk if this is a brain tumor or something else...

Aditional data:

-The eye pain is not correlated with headache.
- The eye pain is only in my left eye.
- The eye pain can affect me for days.
