I can appreciate your concerns and apprehensions. If you were in a car wreck, then probably you have a slipped disc with pinched nerve. Since you are still active, it should not be anything serious, but yes, it would be best to consult the neuro-surgeon.
At the specialist’s office, the doctor will take a detailed history, will examine your neurological reflexes, and maybe ask for a MRI of the spine. Treatment will follow the diagnosis. All the best! Take care!
The medical advice given should not be considered a substitute for medical care provided by a doctor who can examine you. The advice may not be completely correct for you as the doctor cannot examine you and does not know your complete medical history. Hence this reply to your post should only be considered as a guiding line and you must consult your doctor at the earliest for your medical problem.
