Belly hard after 6 months post op tummy tuck. Will it go away? (photos)

Dear Surgeons, I had a tummy tuck 6 months ago. 24 hours after the tummy tuck I had a big bleeding with Hämatoms, that was treated with drains. I had compression 4 months. Under my belly button is my belly hard, big and painful if I touch on. What is it? Swelling? But after 6 months? Fibrosis? I am sad, I hope, that goes away. Does it go away? Will it be okay? I want to have a flat belly. I am 160 cm and 47 kg. Should I have compression again? Thank you if you answer!
