Puffy and Ridge in Pubic Area After Tummy Tuck

In all likelihood, this will resolve.
However, there are conditions which can make this work. I have found that when patients wear garments or binders which fold or kink, especially when sitting, it can make the pubic selling worse due to a tourniquet-like effect.
It is similar to when you wear tight stocklings and your ankles swell.

Thanks for the question.
Post-op swelling after a tummy tuck is still largely present at only three weeks post-op. Swelling occurs as part of your body's natural response to trauma. (Yes, surgery is controlled trauma!) Your body has an impaired ability to resolve this swelling because of the divided lymphatics.
Your surgeon may have used drains for the first week or two to collect fluid accumulating under the abdominoplasty flaps.
Most of this swelling should go away at 6 - 8 weeks.
If the swelling persists it may represent an organized seroma (fluid collection) that will need to be drained, a disruption in the rectus muscle plication or excess fat that might need liposuction.
Time is your friend right now. Be sure to discuss the concerns with your plastic surgeon and have regular follow-up.
I hope this helps.

Three weeks is still early following a Tummy Tuck. A Tummy Tuck incision at the pubic hair line or little below is ok. It is hard to comment on the ridge without seeing it. As long as both skin edges are opposed, you will heal well.I would discuss all these issues with your plastic surgeon he will be able to give you all the correct info.Hope that helps!
