I met with an accident by a car on 12th October 2018. I got many scratches on both legs and 1 stretch on chin. After 5 6 days am feeling pain in my right shoulder joint when moving. Should I take any test to check for any internal injury. If so, what test will be required to check for both knees and shoulder. I want to know the name of tests or simply X-ray of legs and shoulder will be fine to check any internal injury? On shoulder, I don't have any scratches above knee, below knee part was hit by car. No fracture.
