Atrophied scar revision at 6 months? (Photo)

My last drain was taken out far too early (90ml per day, on average over 5 days before removing), I had a huge seroma burst 6 days after removing the drain, It took a month to heal, in the spot where i had regular dressings and compression it has essentially indented and the scar has heal atrophied. I was told at 4 months to wait, 6 have now passed. I'm adamant this needs sorting now, I'm not swollen anymore, but the problem side seems far worse in general. I love the good side, HATE the bad side
