Surgeon persists I wear underwire post BR. Is this normal?

As other doctors have stated, every doctor is different, and you should defer to your doctor's recommendation.I love underwire bras after breast reduction. Why?I do the short scar technique, so an underwire isn't running along the scar line (like it does on an anchor scar).I think underwire bras are just better supportive bras.You will swell to fill whatever shape you put your breast into right after surgery.  An underwire helps make sure you are supported in the right places and shape.It should be comfortable.  If it isn't, maybe try a different size or brand.

First of all, congratulations on your breast reduction surgery, kristy9230!
Although it’s unusual for your surgeon to ask you to wear an underwear bra post-op, please remember that every plastic surgeon has his own protocol regarding that. There’s no hard and fast rule for such.
However, wearing an underwire bra while you’re still healing might be uncomfortable. It can also irritate your incisions. Let your reputable and board-certified plastic surgeon know of your concerns so that he can do something about it.
Good luck!
