Early symptom were gradual loss of hearing. I was also having mild dizzy spells around the time of initial consult with an ENT, but did not associate those with the tumor. Similarly, there were other problems that had built up over the years that I had not recognized as symptomatic until well post-surgery from the large mass compressing my brain stem.
Seriously though, Jim is absolutely correct in his suggestion "Unscientific speculation will only serve to confuse you." Wait for the MRI as there could be other explanations.
Even if you do have tumor, no matter how many of our stories you read here, your journey will be different. It will be uniquely yours. I know the waiting is hard. It was hard for me between the diagnosis of the possibility of a tumor and the MRI. The four days after the MRI after being told there was tumor by the radiologist and the actual consult was bad. Waiting can just suck.
If reading this stuff helps with the waiting, then good. if not, maybe a good Stephen King book will take your mind off of things.
