Seroma seroma

Last week I had 120mls (~40oz.) drained from the seroma that developed at my surgical site. Then it developed again so I went back in and I now have another drain. I'm not quite convinced the PA really knew what she was doing since she didn't put a dressing over the drain tube site. Sutured it in and that was it. Wouldn't be so concerned if I hadn't had to go thru FOUR MONTHS OF ANTIBIOTICS for an infection!
