MVA Breast rupture concerns, is it okay to go to primary care eval on Dec 19th?

I was rear ended and forced into the car in front of me on the freeway. I’m short and sit all the way up to drive. On impact my chest hit the steering wheel and knocked the air out of me. The initial pain I had immediately was a burning sensation all throughout my chest. I was diagnosed with chest contusion and whip lash at urgent care. Chest X-ray was normal. My plastic surgeon said to go to primary care for eval, and that’s not until Dec 19.. is this the right course to take? I am anxious.
