what would you do?

Yesterday afternoon we noticed this yearlings nodes below her jaw slightly swollen, which to me signifies that she's fighting an infection. No other symptoms whatsoever, stools fine, no coughing, no loss of appetite, nothing. As of now I'm not doing anything except watching her closely for other symptoms to appear but I was just curious as to what some of you would do in this situation or what your thoughts might be?

Long lasting antibiotics such as Draxxin (2 or 3 ccs) or Tetradure (6 or 8 ccs) would be my choice. It does look more like a swollen gland than it does a pus sack.
