I was hit with a softball in the nose yesterday and seems it left a bump will it be permanent yes or no?

Anytime there is trauma to the nose, it's important to visit an ENT facial plastic surgeon to determine whether not the external nasal bones have been broken, the septum internally has been broken, or the upper lateral cartilages have been dislocated off of the nasal bones. It's also important to get x-rays to document any potential nasal fracture.

Since you were just injured yesterday, you will need to give your nose time for swelling to dissipate. It usually takes several weeks, and in some circumstances, months, before all temporary effects of trauma have resolved. I would consult with an experienced rhinoplasty surgeon in your area who can follow your progress. Good luck!

Your nose will need evaluation to answer your question.  If any bones are broken or you have internal injury to your nose you will need treatment.
