Im 3 and 1/2 months post op. For the past few days a little section of my scar seemed irritated and raised a bit. I think it was from brushing my hair too aggressively. Well today i was checking it out and tapping it and all of sudden. it started to bleed and a bit of puss came out. After squeezing all the blood and puss out, the scar flattened a bit. Does anyone know why this mightve happen. Will this affect how my scar heals?
