Treatment

I think this is funny. I was already when my teacher asked me question about the things that she discussed to me. It's almost one o'clock when she tested me. She has what hx stands for. I said history, dx stands for diagnosis. She then asked me what tx stands for. I had a mental block. I can't think what it stands for. So I said, tx stands for message as in text message. She laughed so hard and she decided that we will call a day :-).
