Brielle Biermann looks like she’s had a rough couple of weeks following surgery, but she says recovery’s actually going smoothly … and she can’t wait to eat pizza like a normal person.

Kim Zolciak-Biermann’s daughter says she had double jaw surgery a couple weeks ago, but that it was NOT an aesthetic procedure … but to improve her quality of life.

According to the “Don’t Be Tardy” star … she suffered from TMJ and a significant overbite due to sucking her thumb for years, which resulted in her having major biting and breathing issues.

Brielle writes … “Have you ever thought about what it’s like to not be able to bite into pizza? or omg trying to bite into an onion on a burger? impossible for me. I had to use my tongue to help me chew and almost choked every time I ate.”

So, she says she needed the surgery to correct her problems but was very scared, but her family, friends and support system came through for her … along with her doctors.

Brielle says the first 2 weeks of recovery were supposed to be the hardest, but it’s been “easy breezy” … despite what the photos and videos she posted suggest!!!

It seems like the surgery was a success, and if all goes well she’ll be able to eat pasta and soft foods in a few more weeks … and chomp on some pizza in 3 months. She says she’s counting the days.
