Linda,
I had a scare from a suspicious node once or twice myself. One time they told me that I shouldn't worry, that when I came back to MDACC in three months for another CT scan they would look at it and see if it had changed size. I said "B.S.!" and called my cousin who is a radiologist and owns a couple of imaging clinics. He gave me a PET scan but, fortunately, the docs at MDACC were right...it was nothing to worry about.
Naturally those of us who have gone through this stuff get nervous when anything happens that is weird, especially in the head and neck area. I worried when one of my eyes was tearing and went to an opthamologist, worried once when I got dizzy getting out of bed, and worried when the dentist found a little spot on my tongue. We need to be constantly vigilant but not worry too much.
I am glad that your recovery is going so well Linda.

Take care,
Danny G.
