Brain tumour fears

Hello all,i have posted on here numerous times about body tremors(which i am still getting) but a new symptom this past month is visual disturbances in BOTH eyes!!!i am seeing billions of black dots in my field vision,they look like tiny cells moving around under a microscope!!these are not floaters as i know what they are,the vision is also fuzzy snd looks like a light is flickering.i have seen 3 opthamologists who have checked front and back of eyes and can not see anything wrong.which makes me think this is brain related with the head tremors ive been getting.constant jerking finger in left hand and dizziness!! Ive seen numerous doctors who have dismissed this due to anxiety!!id agree with them but theres no way these visual issues are stress and anxiety!!!i have orderd an mri scan but wont be for a couple of months.im convinced i have a brain tumour im going out my mind with worry,has anyone ever heard of these eye problems?the millions of black dots(cell like)moving in vision?thanks

Potter,

I have had the black spots when I have hyperventilated. Is it possible that you are unaware of some anxious breathing going on, due to stress? Anxiety sufferers can have symptoms from chronic shallow/overbreathing.

Try spending several minutes, 3 times a day practicing slow, steady deep breathing exercises...and see if this makes a difference.

Peace, progress and keep us updated!
