hey Cynaburst. I had a shunt a minute before my surgery. Than it was out for 12 hours. I have 2% of the tumor on my brain stem, and i get an MRI every year to be sure it has'nt grown. If it does I have to get spot radiation.I have no hearing on my left side due to the tumor and I have imbalance issues. Its not dizzyness, its like my head is floating all the time and noise is now amplified. Wind and rain, barometer changes cause issues for me.
