Hi /sci/

I'm asking for your help. I've been having headaches every evening for a long time, I'm always tired, sometimes I feel dizzy and my pupils go pinpoint size then back to normal. My vision is getting blurry and sometimes I see things in double. My arm and a point in my back always feel numb.

I've been at the doctor to find out what's going on, he didn't know so he sent me to hospital where they did an MRI scan. Today I've got a text saying: "Ask for an appointment as soon as possible to discucc your results"

How fucked am I? Can it be brain tumor? Am I going to die? Please help, I can't sleep and I have the appointment two days from now, I need to know what to expect

Are phosphenes induced from the Valsalva maneuver brain or retina derived?
