Hi teetee503, I was told that I have 3mm tumor last April 2012 which has grown to whopping 3.5mm in early Jan this year 2013. I have had a lot of problems with this little sucker,headaches, earaches , fullness all the time , some tinnitus , but the worst thing is my balance, I walk like I am drunk and sometimes my trunk rocks back and forth or sways. I have been to many neuro's and been told the same thing that this small tumor shouldn't be giving you that much troulbe. I am on my second round of vestibular therapy at Rusk Institute @NYU and that has been somewhat helpful , but no real cure, I just try to block it out most of time and go on with my life. It is a little harder to stay in the shape that I was in because the balance issues tire you out , your body is working overtime to keep itself upright. One ENT told me that she thought the tumor might be really pressing on the nerve, which is something the doctors can not really tell. If you can get to a surpport group they are very helpful. If you would like to chat some more feel free to contact me , hopefully I could be of some help. Good luck and be well.
