Why Pain Goes Away After Taking A Painkiller: Pain is an important signal of our body, which warns us about some injury or internal problem. But when this pain becomes severe or persistent, then to reduce it, people first resort to painkillers. In such a situation, the biggest question is that how does the pain reduce after taking painkiller and how fast does this medicine work.

What does a painkiller do?

According to neurologist Rebecca Seal and anesthesiologist Professor Benedict Alter, who studied pain, pain does not come directly from the place where the injury occurs, but special nerve cells in the body sense the injury or swelling and send signals to the brain. The brain understands these signals as pain. This is the reason why painkillers work not on the root of pain, but on stopping these signals.

How does painkiller work?

When you take a painkiller, the medicine dissolves in the stomach and spreads throughout the body through the blood. Usually its effect starts within a few minutes, whereas some medicines can take up to an hour. These medicines reduce the chemicals produced in the body, which are responsible for swelling and pain. For example, drugs like ibuprofen and aspirin weaken pain signals by blocking the COX enzyme.

direct effect on the nervous system

Some painkillers directly affect the nervous system and slow down the pain signals reaching the brain, while some medicines activate the natural endorphin system present in the body, which reduces pain. This is the reason why different medicines are given for different types of pain. However, it is important to understand that not every painkiller has the same effect on every type of pain. There are many paths and causes of pain, so the effect of medicines can also be different. Experts say that painkillers provide immediate relief, but their excessive or prolonged use can also cause side effects. Therefore, one should avoid taking medicine without doctor’s advice.
