Minor mishaps like choking, neck strain, leg cramps, or numbness can happen anytime. Some of them are harmless, but others—if handled incorrectly—can become dangerous. Here are science-backed first-aid responses you can safely use in daily life.

1. If Someone Is Choking

What really helps:

• Encourage the person to cough forcefully if they can still breathe or speak.

• If they cannot breathe, speak, or cough, perform the Heimlich maneuver (abdominal thrusts) or call for emergency help (911, 115 in Vietnam).

• If you are alone and choking, you can lean forward over a firm chair back or table edge and press sharply inward on your upper abdomen.

Raising both arms, as sometimes suggested in folk stories, may not help dislodge an obstruction—but staying calm and reacting quickly can save a life. (Source: American Red Cross First Aid Manual, 2024).

2. Stiff Neck or “Crick in the Neck”

Waking up with a stiff neck is common and rarely serious.
What helps:

• Apply a warm compress or take a warm shower to relax the muscles.

• Gently stretch the neck from side to side, holding each stretch for 10–20 seconds.

• Maintain good posture while sitting or sleeping.

Avoid twisting or sudden movements. The old tip of “rotating your toes” or “lifting your foot” has no proven effect. (Mayo Clinic, Neck Pain Self-Care, 2023).

3. Muscle Cramps (Leg or Foot)

A cramp happens when muscles contract suddenly and painfully.
Do this:

• Stretch the muscle: For calf cramps, straighten the leg and pull your toes toward your head.

• Massage the area gently, and drink water or an electrolyte beverage if you’ve been sweating.

• Regular stretching before sleep or exercise helps prevent recurrence.

The idea of raising the opposite arm may distract your brain and ease tension briefly but is not medically proven. (Cleveland Clinic, 2023).

4. Numb Legs or Tingling

Usually this comes from temporary nerve compression (sitting cross-legged too long).
Do this:

• Stand up, move around, or shake your legs gently.

• Avoid staying in one position for long periods.

• If numbness persists, see a doctor—chronic or one-sided numbness may signal a nerve or circulatory issue. (Johns Hopkins Medicine, Peripheral Neuropathy Overview, 2024).

⚠️ 5. Dangerous Myths: Using a Needle to “Draw Blood” in Stroke or Heart Attack

Some online sources or old folk remedies claim that pricking fingers, toes, or ears with a sewing needle can “release bad blood” and revive someone having a stroke or cardiac arrest.

⚠️ This is false and dangerous.

According to the World Health Organization and American Heart Association, the correct actions are:

• For suspected stroke: Call emergency services immediately. Note the time symptoms began. Do not prick, slap, or shake the patient. Keep the airway clear and help them lie on their side if vomiting.

• For suspected heart attack or cardiac arrest: Call emergency help, start CPR (chest compressions) if unresponsive and not breathing, and use an AED if available. Every minute without CPR reduces survival chances by 7–10%.

Needle pricking wastes the crucial “golden minutes” and can cause infection. (WHO, First Aid for the Public, 2024; AHA, CPR Guidelines).

6. Breathing Difficulty or Asthma Attack

If someone is gasping or wheezing:

• Help them sit upright and use their prescribed inhaler (blue reliever inhaler for asthma).

• If symptoms persist longer than 10–15 minutes or they can’t speak in full sentences, call emergency services.

• Never pierce the nose or skin with a needle. (CDC, Asthma Emergency Response, 2024).

Final Advice

Every household should:

• Keep a basic first-aid kit and learn CPR.

• Save local emergency numbers (115 in Vietnam).

• Avoid unverified internet “life hacks” involving needles, cutting, or heating.

Real first aid is about time, calmness, and proven methods—not improvisation that can make things worse.
As the Red Cross reminds: “Do no further harm, and call for help early.”
