I started T in my forties, but my hands did grow a little. It's not really noticeable if you look at them. In fact, the only reason I know that they grew is that I used to easily slide my hand into certain drinking receptacles when I was washing the dishes, and now I have to jam my hand in and struggle to get it out again.
My feet are not bigger, as far as I can tell. In fact, for a little while, I thought they might have shrunk a little. I finally decided that they had simply stayed the same. My confusion was due to sizing anomalies in my new shoes.
