Quick answer

If someone has lost consciousness even briefly, keeps vomiting, has a worsening headache, has a seizure, slurs their speech, or becomes hard to wake, treat it as an emergency and call SIEHS-1122 straight away.

A person can seem theek thaak (fine) right after a fall or a road accident, and still be seriously hurt. Head injury symptoms after an accident do not always show up straight away; some appear within minutes, others take hours or even days to surface, by which time real damage may already be building up inside the skull.

A hard enough impact makes the brain move inside the skull with no visible wound at all, so never judge how serious it is by how much blood you can see. Children, older adults, and anyone on blood-thinning medication need extra monitoring, even if they insist they feel fine.

What Are the Common Head Injury Symptoms After an Accident?

Milder early symptoms include headache, dizziness, nausea, blurred vision, sensitivity to light or noise, tiredness, brief confusion, patchy memory of the accident, and irritability or a mood change.

These still deserve a proper checkup, since a mild headache at first can later turn into confusion or unsteadiness.

Any one of these means: call 1122 now
  • Lost consciousness, even briefly, or has not come round since the accident
  • Become hard to wake, or is growing more confused or agitated
  • A severe or worsening headache, or repeated vomiting
  • A seizure or fit, or slurred and unclear speech
  • Weakness or numbness in the face, arm or leg, or trouble walking or balancing
  • One pupil larger than the other, double vision, or sudden loss of vision
  • Blood or clear fluid from the nose or ears, or bleeding that will not stop
  • A visible dent, deep wound, or object lodged in the head
  • Trouble breathing, or neck pain after the impact

Most of these match the danger signs listed by the CDC; fluid from the ears or nose and a dent or object in the head also appear in NHS head injury guidance. Do not wait to see if these improve.

A minor scalp injury stays on the outside; concussion symptoms are different, since a concussion is a mild head trauma after an accident where a blow or jolt makes the brain move inside the skull. You do not need to lose consciousness to have one.

Where the injury isOn the outside of the headInside the skull, the brain moves after a blow or jolt
Visible wound?UsuallyOften none at all
Knocked out?NoNot required to have one

An untrained person cannot tell the two apart by looking, so if awareness, memory, balance, speech, or behaviour is off, get it checked.

Head Injury Ke Baad Ambulance Kab Bulani Chahiye?When head injury symptoms after an accident need an ambulance

Call 1122 straight away if the person is unconscious or hard to wake, if serious force was involved such as a high speed collision or a fall from height, if symptoms are worsening, if a neck injury is possible, or if safe transport by private car is not possible.

Brain injury signs can exist even if the person is still talking, and a badly damaged helmet is a clear sign the impact was forceful enough to call.

What Should You Do While Waiting for the Ambulance?

  1. Keep the person still and support the head in the position it is found in.
  2. Check breathing and ask their name, where they are, and whether they can move their hands and feet. Tell the call handler about any change.
  3. Control bleeding with a clean cloth, but never press on a suspected skull fracture or an embedded object.
  4. Skip food, drink, or medicine, and leave a helmet in place unless CPR is needed.

These steps match Mayo Clinic head trauma first aid guidance.

Common Mistakes, and Extra Care for Children and Elders

Talking normally does not mean someone is safe. Avoid letting the injured person drive, leaving them alone, or moving them despite possible neck trauma. “Ho jayega theek” (it’ll be fine) does not apply here.

Children often cannot describe symptoms clearly, so watch for persistent crying or poor balance. Older adults on blood-thinning medicines carry a higher bleeding risk after even a minor fall.

When calling 1122, tell the call handler:
  • The exact location
  • What happened
  • Whether the person lost consciousness
  • Their current symptoms
Q1. What are the danger signs after a head injury?

Call SIEHS 1122 straight away if the person lost consciousness even briefly, is hard to wake or increasingly confused, has a worsening headache or repeated vomiting, has a seizure or slurred speech, has weakness or numbness, has unequal pupils or vision loss, has blood or clear fluid from the nose or ears, or has a dent or object in the head.

Q2. Can head injury symptoms appear hours after an accident?

Yes. Some head injury symptoms appear within minutes, while others take hours or even days to show. A person who seems fine right after a crash or fall should be watched closely, and anyone whose symptoms get worse needs emergency help from SIEHS 1122.

Q3. Do you have to lose consciousness to have a concussion?

No. A concussion happens when a blow or jolt makes the brain move inside the skull, and most concussions happen without the person being knocked out. Any change in memory, balance, speech, awareness, or behaviour after a head injury should be checked.

Q4. Should I drive someone with a head injury to hospital myself?

If there are danger signs, if serious force was involved such as a high speed collision or a fall from height, if a neck injury is possible, or if you cannot transport them safely, call SIEHS 1122 instead. The injured person should never drive themselves.

Q5. Are older adults on blood thinners at higher risk after a fall?

Yes. Blood-thinning medicines raise the risk of bleeding inside the skull, even after a minor fall. Older adults on these medicines need prompt medical advice and close monitoring after any head injury, even if they say they feel fine.

Q6. Is the SIEHS 1122 ambulance free in Sindh?

Yes. SIEHS 1122 is a free emergency ambulance service available 24/7 across all 30 districts of Sindh. For medical advice when there is no emergency, call Tele-Tabeeb 1123 for a free consultation with a doctor.

Recognise the Signs and Call 1122

Do not wait for someone to collapse before calling for help. Serious brain injuries are not always visible, and a person can look stable and still get worse within hours.

If someone in Sindh shows any danger signs after a road crash or fall, call SIEHS-1122 for a free emergency ambulance. Early assessment is what actually reduces the risk of lasting harm.
