Do I need to have otoplasty suture removed & will I lose my otoplasty results? (Photos)

I am 8months post op. I figured the lump behind my ear was the suture. I recently sat in a steam room for 10 min. That night, realized my ear was bothering a bit more than usual. I gently cleaned the area with a wet qtip but I guess it cut the skin. It started bleeding(pic1) I cleaned and put Neosporin. The next morning, the area was full of puss(pic2). I cleaned it and continue using Neosporin(pic3) and the area completely healed. But now, a week later, it seems the lump is back (pic4)
