Can I have my tummy tuck undone? It's been 4 years since my surgery and I still have issues breathing and am pulled very tight.

What does a tummy tuck "undoing" entail, and will it be as invasive as the actual tummy tuck? Can the sutures be taken out through your belly button, instead of having to be cut end to end? its been 4 years but I still feel short of breath & miserable in my own skin. I've been to a couple other surgeons (I don't want to see my original surgeon anymore because of the damage already done), and they tell me it's in my head. Anyone know a doctor who has done the tummy tuck "undoing" procedure?
