The brain does not feel pain – why? 4 minutes Have you ever felt the pain that makes you think your brain is exploding? According to science, everything in the body can hurt, except for the brain itself, which does not feel pain. Keep reading to learn more about brain sensitivity!
The brain is the organ responsible for processing pain, integrating incoming information through the nervous system, and interpreting all of these signals. But interestingly, the brain itself doesn’t feel pain.
Pain is an important warning sign of injury. And this sets in motion the natural mechanisms for solving the problem. It does this through a series of nerve endings that pick up signals.
These nerve cells are called nociceptors, commonly called pain receptors. and they receive sensory information from both the outside and inside of your body. They are located at the ends of axons (nerve fibers) in sensory nerve cells and can transmit impulses to the brain. In addition, they can transmit information about mechanical, thermal or chemical damage to the entire nervous system in tenths of a second.
Why doesn’t the brain feel pain?
Paradoxically, there are nociceptors in the brain, but the brain itself does not feel pain. However, he is far from understanding the benefits of this for human survival but allows neurosurgeons to operate on the brain only under local anesthesia.
Thus, the patient can stay awake during the operation. This is an advantage because the patient can confirm that everything is going well.
You may feel like your brain hurts or you feel like it will explode when you have a headache. But what you actually feel is the nerve tissue, meninges, blood vessels, and muscles around the brain.
These parts, which have nociceptors, can become inflamed, damaged, or enlarged. They then send an alarm to the brain that something is wrong, which in turn leads to widespread headaches. In cases like brain tumors or cerebral hemorrhages, when pain is recorded, it still does not come from the brain. In fact, this is due to the pressure created by the surrounding blood vessels.
Pain in the brain and headache
Usually, headache is not a critical condition, but usually due to tension headaches, migraines, sinusitis, or neck inflammation. The head can also ache from colds, flu, or other viral diseases that cause poor blood flow or inflammation.
However, there are other more serious problems that can cause pain. Here are some of them:
- Abnormal connection between arteries and veins in the brain.
- A cardiovascular disorder that stops blood flow.
- Broken blood vessels or arterial hernia (aneurysm). </ li>
- Cerebral hemorrhage or intracerebral hematoma.
- Cerebral hemorrhage: subarachnoid, subdural or epidural hemorrhage.
- Very high blood pressure.
- Infection. brain or nearby tissues.
When should I see a doctor?
Because the brain does not feel pain, headaches are the main symptom that signals damage to this organ. However, not all types of headaches indicate something serious, as stated above.
You need to know when this pain can actually be caused by serious causes, so you know when to see a doctor. Therefore, you should contact healthcare when:
- Pain interferes with your daily life.
- It gets worse after exercise.
- Occurs suddenly and explosively.
- This is true. are associated with changes in vision, mobility, language, or memory.
- The condition worsens after 24 hours.
- It is manifested by other symptoms such as fever, stiffness, or nausea.
- The eyes turned red.
- You have or have had cancer or have a weakened immune system.
- The headache wakes you up and you cannot sleep again.
Thus, when you experience a headache, it is in the tissues, blood vessels, and muscles of the brain. As you can see, although it is responsible for handling pain and pain, the brain itself cannot feel pain.
Therefore, if you have an atypical headache, you should consult a doctor who can determine if it is caused by trauma to the surrounding tissue or a problem inside the brain.
