WTH! My incision got infected!

(Let me preface by saying that I see my doctor today)

Okay but WTH… i wake up this morning and notice a white lump on my incision. I dab some paper towels on it and sure enough it’s puss. … … ugh.

Has anyone else had this happen before?

I’m almost a month post op. The infection seems to be localized to the area on the incision where a stitch broke through.
