9 months after tummy tuck - Sore on epigastric area with ball feeling underneath skin.

Hi, I had full tummy tuck last November. Recently, I have been feeling sore on my epigastric, even more sore when I touched it. It felt like ball underneath my skin. I went for ultrasound check, it showed blood flow in two areas. Then I went to see my plastic surgeon for examination. She felt it and said it’s suture. A I suppose to feel like this forever? It’s hurting and bothering me.
