No longer taking steps

On 15th of Feb, my daughter took her first steps unaided.

A couple of days ago, she started teething - temps, mucous poop, puffy eyes, swollen gums, sore ears....(she hasn’t been anywhere to catch a virus).

And since then, she still stands and whatnot, but she doesn’t want to walk. She walks along the furniture still, but coaxing her to walk unaided, she just sits down and cries because I won’t give her the toy or food.

Is this normal? Should I see someone?
