What should I do?

It would not go well if your employer fired you for reporting your injury. In New York. that is illegal!

I was in route straight to my home. Sober! Will pass drug test and not had accident in over 10 yrs. I worry that if I start an injury claim it will have negative effects.

At the scene I turned down medical attention because I thought I was fine. It must of been adrenaline. Few hrs later back mostly is tight and sharp pinching pain. Worried I should have got medical attention. I cut the ends on front bumper off with battery powered saws all at scene cause it was pushed back onto front tires. Was trying to save a tow. Only 3 miles from home
