I'm Will Like to Know Do I Need a Tummy Tuck Revision Done? (photo)

I had a tummy tuck done 2 yrs ago and I'm not happy with it. I seem to have too much extra skin, bulging here and there, and somehow formed a scar tissue which makes my stomach looks lopsided and not flat as i hoped to be. My navel still looks like I had surgery which just Maybe the way my body heals. I was told give it sometime and I gave it two yrs and still no change. I workout fluently with very little change from the bulging. Please advise,thanks!
