You legally only have so much time after an accident to be evaluated by a doctor.
Exact time varies by state. Usually 48hrs or something like that.
After that time, your insurance company can deny future claims- as you will be found partially at fault for delaying care.
You may or may not need xrays- but I would recommend you be evaluated by a doctor, er, walkin clinic, etc. Just need the paperwork trail.
Good luck
