Hi Everyone, I am new to Radiation section because I was on W and W for about 5 yrs. My tumor was very small for many years 3 mm in 2012 to about 6mm x 5mm x4mm in 2016 MRI scan. I had Gamma Knife Radiation at N.Y.U with Dr.Kondziolka team last Wednesday so it only a week. The 1st 2 days no real problems minor headaches at pin sites my usual pressure fullness earaches, by Saturday my hearing in effected ear was shot and sounded as if everyone was underwater. I have always had balance issues and very mild hearing loss . The balance issues were if I felt I just got off a ship, but now I am experiencing more like spinning feeling the vertigo feelings everyone has talked about. I am currently on steroids, Methylprednisolone 4mg cycle just started the other day. I took my shot with G.K to clear up my problem and reduce the chance of the tumor creating single sided deafness, so I can only hope that it's early in the game and things will get better, any suggestions or similar experiences are welcomed. I have been to Vestibular Therapy before so I am hoping that will be next if nothing else changes. Thanks in advance . All the best and God bless!
