Puss/Clear fluids coming out of my scar?

I ruptured my achilles and had surgery almost about 6 months ago. I have been doing fairly well up until about 3 days ago when my scar was very sensitive to the touch. One spot has technically never fully closed up. It had bleed a little about 2 months ago but very little. Last night I noticed that clear liquid was coming out (very slowly) I put pressure on it and puss started to come out. I iced it and tried to push the puss out. I don't know if that was a good idea or not, but it feels better. I could barely walk last night it was hurting so much. I am trying to get an appointment with my doctor, but in the mean time....has this happened to anyone??
