Necessity of pain

 

Pain is painful but it's unavoidable. Nobody likes pain but still, we all experience pain in some form or other from time to time. Pain may be a necessity in our life. we won't live without pain because it serves a really important role in our day-to-day life. It's our body's early warning system that something is wrong, so that steps may be taken to correct the matter. as an example, if you by mistake touch a hot stove or if a mosquito bites you, the nerves in your skin shoot a message of pain to your brain. The brain immediately sends a message right down to the acceptable muscle in your hand to contract, thus pulling away from your hand. In absence of pain, you may find yourself burning your hand. Thus pain motivates us to withdraw from damaging situations, to guard a damaged part while it heals, and to avoid similar experiences within the future. Pain could be a major symptom in many medical conditions.

What Is Pain

Pain is an unpleasant sensation that hurts. it's often caused by injury, disease, or emotional disorders in varying degrees of severity. Pain will be steady and constant, within which case it should be an ache. it would be a throbbing pain - a pulsating pain. The pain could have a pinching sensation, or a stabbing one.

There are two basic kinds of pain, acute and chronic. Pain that lasts an extended time is named chronic, and pain that resolves quickly is named acute. If not properly taken care of and treated, acute pain can become chronic pain. Chronic pain persists or progresses over a protracted period of your time.

Pain may be classified into -

1. nociceptive pain is caused by stimulation of peripheral nerve fibers that respond only to stimuli of harmful intensity (nociceptors). it's going to be specified consistent with the mode of stimulation; the foremost common categories being "thermal" (heat or cold), "mechanical" (crushing, tearing, etc.), and "chemical" (iodine during a cut, flavoring within the eyes). 
2. Inflammatory pain is related to tissue damage and therefore the infiltration of immune cells.
3. Pathological pain could be a disease state caused by damage to the system or by its abnormal function (tension-type headache, etc.).

The Pain Process

Pain is a vital part of our life - vital to our healthy survival. it's a part of the body's arms, producing a reflexive retraction from the painful stimulus, and tendencies to safeguard the affected piece while it heals, and avoid that harmful situation within the future.

Our systema nervosum is split into the central system (CNS) made from the brain and neural structure and therefore the peripheral system (PNS) which consists of all nerves that vary from the medulla spinalis and form a network throughout the body.

Nerves cells (called nociceptors) sensitive to stimuli like temperature (hot and cold), pressure (e.g. hitting, pressing, squeezing, caressing, etc.) and chemical changes are present all around our body. When cells in our body are injured or damaged, they release a chemical called prostaglandin. The special nerve endings that sense pain are very sensitive to the current chemical. They immediately inform the brain about the stimuli (like touching something hot) by sending electrical signals to the thalamus via the medulla spinalis. The brain processes this information (like a variety of stimuli, location, what proportion it hurts, etc.) and sends a response signal through medulla spinalis and motor neurons to the placement telling muscles to require necessary action (like pulling far away from the recent object). All this happens very quickly, in a very fraction of a second.

Thus pain is an alarm that alerts us about potential or actual damage to our body. This causes us to leap into action straight away and stop additional health complications. In absence of pain, anything could get it wrong, and that we won't even come to understand about it.

Pain Killers

When we suffer from pain our doctor gives us a medication called analgesic (popularly called pain killer). An analgesic could be a drug wont to achieve analgesia i.e... relief from pain. the foremost popular pain relievers are ibuprofen. acetaminophen, nimesulide, paracetamol etc. These drugs act on the peripheral and central nervous systems, specifically nerve endings, to stay us from feeling pain.

When we take some pain relievers like ibuprofen, it keeps injured or damaged cells from making and releasing prostaglandin. When the cells don't release this chemical, it means the brain won't get the pain message as quickly or clearly. So your pain goes away or becomes less severe for as long because the cells aren't releasing the chemical.

If somebody has an operation or another unhealthiness that causes lots of pain, doctors may prescribe pain relievers that are stronger than acetaminophen and ibuprofen. These sorts of pain relievers work by going in between the nerve cells so that they can't transmit the pain message to 1 another. The message isn't able to make it to the brain, and this keeps the person from feeling pain.
