Hello I'm 23 years old and this is my 3rd absess the first two was on my left breast and they hurt but I never felt sick on the stomach or anything but I've recently had one on my right butt cheek and it make me feel sleepy, ill, have headaches on my left side,and made my top right gum hurt. It busted on its on and still having pus coming out but all the symptoms have stopped but the feeling sick to my stomach. Does anyone know why this happens or why it made me feel this way?
