What to know
Symptoms after a car accident do not always begin at the scene. Neck pain may become more noticeable later, and concussion symptoms can emerge over hours or days. There is no universal 24-to-72-hour window that determines whether an injury exists or whether it is safe to wait. AAOS neck symptom guide, CDC symptom timing
Respond to changes rather than the calendar
If you develop new symptoms, seek medical advice about an appropriate evaluation. Tell the clinician when the crash occurred, when you first noticed each symptom, and what has changed. Avoid assuming that a later symptom is harmless or that every later symptom necessarily came from the collision.
Write a brief timeline while details are fresh. Include the body area involved, activities that have become difficult, and care already received. For example, record that neck pain began the next morning and now limits turning your head, rather than trying to assign your own diagnosis.
Know when follow-up becomes an emergency
New trouble urinating, loss of bowel or bladder control, groin numbness, or rapidly worsening leg weakness needs immediate emergency evaluation. These can indicate serious nerve compression. AAOS cauda equina guidance
Call 911 for other emergency signs such as difficulty breathing, fainting, severe worsening pain, or a person who cannot be awakened. Do not use an appointment request form for an emergency.
Keep useful medical and accident records
Keep discharge papers, prescriptions, imaging reports, bills, and a record of missed work or activity restrictions. The Texas Department of Insurance recommends retaining medical records and bills and documenting collision details. Prioritize safety and medical care before collecting photographs or paperwork.

Texas crash-report rules are separate from medical decisions. TxDOT explains that an investigating officer must submit a report for a crash involving injury, death, or apparent property damage of at least $1,000 to any one person. That reporting threshold is not a threshold for seeking care. TxDOT crash reports and records

Common questions
Frequently asked questions
Should I still mention symptoms that have improved?+
Yes. Describe their timing and course so the clinician has a fuller history.
What should I bring to the appointment?+
Bring available records, medications, prior injury information, and your symptom timeline. Review our first-visit guide for more detail.
How long after a car accident can symptoms appear?+
Symptoms can appear hours to days after a car accident, and they commonly show up within 24 to 72 hours. Adrenaline can mask pain at the scene, so neck or back pain, headache, dizziness, or numbness may be noticed later. A delayed start does not by itself prove or rule out an injury. Whether the symptoms relate to the crash is determined by clinical evaluation.
Should I see a doctor if pain starts days after a crash?+
Yes. Get evaluated if pain starts days after a crash, and tell the clinician about the accident. Delayed neck pain, back pain, headache, dizziness, or numbness can still deserve a medical history and examination. Mention when the crash happened and when each symptom began. The next step depends on clinical evaluation, and emergency symptoms need emergency care.
