Hi
You will get lots of support here. My tumor is 22mm, the size of say a quarter. If that gives you something to compare the golf ball, to.
Anyway, yes the knowledge is power and see the surgeon, radiologist, do your reading and ask all questions you want on the forum.
It is hard and I know what you mean about the facial numbness and tingling. I have that also. I did have CK but it's only been three months. (no real change yet) One thing that hit me hard when reading your symptoms, which I have all of the symptoms you mention except the one change, is the fullness seems less for me) I do have water behind the eardrum now since Jan. 1st which is painful. There isn't room in there with the tumor for the water, the doctor mentioned. (ENT doc)
I'm typing this at midnight so, it might not make as much sense as, in the later morning. I need to get back to bed. I wanted to respond to you.
Hang in there and we will be there for you. You will get through this and your health is the most important thing for you now. Yes, you have children and take this one step at a time or it is over-whelming. I don't know where you live or the type of work you do but, you will get there.
I'm supposed to get another MRI and audiologist test in three more months, then the cons back at Stanford, again. It is a long road and you are now in our club. We will help you.
Hugs,
Palace
