He felt my neck, twice infact and said everything is perfectly normal. I asked him why I thought it had got bigger and he said because I am so aware of things, the smallest change could seem huge to me, he said lymph nodes do indeed change due to infection and viruses and normally people wouldn't even notice.

Why do I not feel completely reassured?
I know he is right of course, if in doubt he would have sent me, he checked it correctly. I measured it 7 months ago length and width and it's still the same, but its the depth that feels bigger. I don't know :(

I'm so confused, he told me, he promised me I am okay, why can't I just accept it and move on?
