I'm 3 weeks post Accutane and I broke out on my nose in a painful pimple , is this normal or should I be worried?

I was on Roaccutane for 6 months on a 40mg Dosage . I'm 3 weeks post accutane and I have a pimple on my nose that is inflamed and painful , am I getting my acne again or is this normal . I'm really devastated.
