May I still know how old you are? I saw your other comment where you said you didn't have any other symptoms as well. Did this tumour not grow? This is so unbelievable. I really should get an MRI soon. I always suspected something in my brain because I had symptoms of stroke like temporary vision loss, temporary loss of control over the body but I didn't do much about it because many others also get this when they suddenly get up from a resting position.
