is this regrowth?

[Paymeinflowers]

Hi All~this is my first inquiry since I became a member in 2005.

I had an 8 mm AN in my left ear treated with radiation after diagnosis in 2005. In the last few months I have been having increased tinitus and loss of hearing. I am also having "internal" ear tenderness and headaches~this is much different than the initial symptoms I had before my diagnosis in 2004. Have any of you had these kinds of issues this far out after treatment? What are the typical (if there is such a thing) symptoms of regrowth? I do have an MRI scheduled on March 9th but am looking for some feedback.
Thank you
