I've already asked if this could be a muscle repair failure, but wanted to ask if it could be anything else. As you can see from pics, lump isn't visible when standing. Only lying down. I had a seroma at 2 weeks PO in that area which was aspirated. Could that be the cause of the hard lump, or maybe fat necrosis? I can feel the hardness to left of my belly button but also behind my belly button if I press inside it. Right side of stomach is soft. Thank you
