I know this is an old post but just thought I would chime in. Wanted to see if anyone else is doing their own fills. I actually am doing my own fills. I will go up no more than 0.5cc every 2 weeks if needed. I do use a special needle, sterile EVERYTHING, and sterile technique. I am a bachelor's prepared nurse and have years of experience accessing ports. I would not recommend it without proper training. I have not had any problems doing my own fills. But, again, I am trained in this and have all needed equipment.
