Please do a see a doctor now. The type of injury you sustained is called a hyperextension-flexion injury of the neck. Most folks make a complete reecovery but a significant percentage of people with these injuries suffer from residual problems. Agressive early treatment reduces the chance of residual problems dramatically.
So first, do make a doctors appointment as soon as possible. On payment, the car in which were driving or a passenger may well have medical payments coverage - that pays medical bills no matter who is at fault. In addition doctors/clinics will often treat and take a lien on the claim for payment of bills.
Talk to a good personal injury lawyer in your town to clarify these issues. You can talk with the best at no expense and then decide how to proceed, including whether to hire the lawyer or another one. Choose a lawyer not by slick ads but by finding a good plaintiff's trial lawyer who specilaizes in representing injured people. Begin with members of your state trial lawyers association or the Association of Trial Lawyers of America.
If you have any trouble getting names, ask me or another lawyer here to get you some names of good local lawyers.
