When you experience sudden pain, your heart rate and blood pressure can rapidly decrease, which affects the amount of blood flowing to your brain. This stress on the body, primarily the sudden loss of blood, can result in fainting or a temporary loss of consciousness.
Examples include the sight of blood, emotional stress, physical trauma, emotional trauma or pain. The stressful event stimulates a bodily reflex called the vasovagal reaction. Your heart slows down and pumps less blood, so your blood pressure drops. Then, your brain doesn't get enough oxygenated blood, and you faint.
Before fainting, it's common to experience some of the following: dizziness. lightheadedness. sweating.
Types of pain scales
Numeric rating scale: This uses a 1 to 10 scale to allow patients to rate their pain. Zero is considered no pain; 1 to 3 is mild pain; 4 to 6 is moderate pain and 7 to 10 is severe pain.
7 – Severe pain that dominates your senses and significantly limits your ability to perform normal daily activities or maintain social relationships.
Level 8 pain is intense, limiting physical activity and even making conversation difficult. Pain at level 9 leaves you unable to converse. You may just be moaning or crying uncontrollably. The greatest pain, level 10, leaves you bedridden or even delirious.
Warning Signs For Simple Fainting
Dizziness (light-headed), blurred vision, nausea, sweating, feeling cold. These last for 5 to 10 seconds before passing out.
Most people will recover quickly after fainting once they lie down as more blood flows to the brain. It also helps to loosen any constrictive clothing. After they wake up, have them stay lying down or sitting for a while longer until they're feeling better.
If someone faints or appears to be fainting, call 911 or your local emergency number. Assist the person by lowering him or her to the ground or other flat surface, while facing up in a horizontal position. Check for breathing and injuries.
Fainting is a temporary loss of consciousness. If you're about to faint, you'll feel dizzy, lightheaded, or nauseous. Your field of vision may "white out" or "black out." Your skin may be cold and clammy. You lose muscle control at the same time, and may fall down.
After four to five seconds, you lose consciousness, stop breathing and have no pulse.
Before fainting, you may have sweaty palms, dizziness, lightheadedness, problems seeing, or nausea. In young people, the problem usually has no serious cause, though falls related to fainting can lead to injury. But in some cases, it can be due to an underlying heart problem that is more concerning.
Fainting is a brief loss of consciousness. Normal awareness returns in less than 1 minute if the person is allowed to lie down. If standing, the person falls to the ground. If sitting, the person slumps over.
If someone else faints
To reduce the chance of fainting again, don't get the person up too fast. If the person doesn't regain consciousness within one minute, call 911 or your local emergency number.
Most fainting will pass quickly and won't be serious. Usually, a fainting episode will only last a few seconds, although it will make the person feel unwell and recovery may take several minutes. If a person doesn't recover quickly, always seek urgent medical attention.
During fainting, “seizure-like” activity may occur. This shaking or stiffening is thought to be distinct from a true seizure and is due to the brain being briefly deprived of oxygen and blood flow. Patients often feel unwell after fainting.
Trigeminal neuralgia
It is one of the most painful conditions known. It causes extreme, sporadic and sudden burning pain or electric shock sensation in the face, including the eyes, lips, scalp, nose, upper jaw, forehead, and lower jaw.
When it intensifies to level 8, pain makes even holding a conversation extremely difficult and your physical activity is severely impaired. Pain is said to be at level 9 when it is excruciating, prevents you speaking and may even make you moan or cry out. Level 10 pain is unbearable.
Here, 0 means you have no pain; one to three means mild pain; four to seven is considered moderate pain; eight and above is severe pain.
The Numerical Rating Pain Scale is a simple pain scale that grades pain levels from 0 (No pain), 1,2, and 3 (Mild), 4,5, and 6 (Moderate), 7,8, and 9 (Severe) to 10 (Worst Pain Possible).
This means that an NRS score in the 1–5 range corresponds to mild interference with functioning, while scores of 6 and 7 represent moderate interference and a score in the 8–10 range corresponds to severe interference with functioning.
About a third of people say they've fainted at least once. Although often harmless, fainting can cause injuries and sometimes signals a problem with the heart or circulatory system. “Witnessing a faint can be scary, because it can look like the person has died,” says Harvard professor Dr. Lewis A.
