You should obtain needed medical care and treatment immediately and follow your doctor's advice. Do not give any statement to the adverse party or insurance company nor grant them access to your medical records. Photograph your injuries and the damage done to any vehicle or other property. Contact a personal injury attorney in your area as soon as possible so that you can protect your rights. You may also find it helpful to review the Legal Guides I have published on Avvo.com dealing with many of the issues you are now facing.
The situation you describe is one where uninsured motorist coverage will protect you. If you have your own automobile which has uninsured motorist coverage on it, you should file a claim with your own insurance company. If you live in a household with another blood relative, you will also be covered under that relative's uninsured motorist coverage, even if they own a separate car and are insured under a different insurance company. If there is such coverage available through a relative, also file your claim with that relative's insurance carrier. Most uninsured motorist coverage extends to resident relatives in the household.
When I say that you should file the claim, you really should have a personal injury attorney do it on your behalf. Your attorney can then guide you through any statements that you may be required by contract to give to your own carrier concerning the incident. Do not give any statements without representation of counsel.
