AT this point in time, I would strongly consider scar revision surgery.
Your result is stable and not likely to change without revision.
I would advise you to leave the umbilical area alone and focus on the scar.
I had a tummy tuck 5 years ago. The surgeon did not place a tummy bandage over the surgery afterwards because " the nurse" forgot to order it? He made shift a dressing bandage . It had jagged edges from the tear. It embedded into the incision site. I had to to return 1week later. I had a hole as big as a quarter. It tooks 1 year to heal completely closed. Scr tissue was thick. I never complained. Just been dealing w/it.
It is a lot less....still..hurts when I stretch/walk/bend. Will it ever go away? Scar tissue is still felt under the the umbilical area. Does the scar tissue ever breakdown on its own after a tummy tuck?

After 5 years you have your final result. Any remaining firmness or scarring that is unsightly will require a surgical revision. Sometimes the fatty tissue under the skin can become firm and if it has not gone away, they speak with you surgeon or a board certified plastic surgeon to review your scar revision options. Some thickened scars can cause chronic pain. You have give it enough time. Now I would recommend seeking a consultation about your concerns.
