Im guessing you went to the doctor already since you have a diagnosis. My question now is, what did they tell you about it.
Is there a cure? Maybe. I had a brain tumor before about 10 years ago. It was big it was actually displacing my left eyeball forward enough that i was experiecing double visions. What i did or my grandma forced me to do was; Cut Meat almost completely off my diet. I was drinking a cocktail of Freshly made vegetable juice. They were a cocktail of carrot, celery, beet, cucumber, sweet potato.
I drank this cocktail for a month 3 times a day. Over the Two month period, i slowly lost the double vision. After 2 months, i got my vision back. When we went to hospital and got an MRI they couldnt find the tumor.
