When you stub your toe or bang your head on a cabinet door, you know you’re about to be in pain. But why do we feel pain, and how can understanding pain help us deal with it? Pain is a response signaling that your body is injured or damaged in some way. Or that something isn’t right, in the case of illnesses, headaches, and other conditions.

Before we get into understanding pain and the types of it, let’s go over the basics of your nervous system. Without it, you wouldn’t feel pain in the first place.


Pain is linked to your nervous system, which consists of your spinal cord and brain. Together, they form your central nervous system. Your motor and sensory nerves, known as the peripheral nervous system, are connected to your central nervous system. Nerves tell your brain what is happening in your environment through the spinal cord.Your brain then sends information back to your nerves so that your body responds appropriately. 

Why Do We Feel Pain? Acute vs. Chronic

Pain comes in two primary types: acute pain and chronic pain.In short, acute pain is short-term and chronic pain is long-term, but there’smore to it than a simple breakdown.

Acute Pain

  • Spraining your ankle
  • Scraping your knee 
  • Breaking your arm
  • Tearing your hamstring
  • Cutting your finger with a knife
  • Getting surgery to fix a hernia 

When your body is injured, the sensory nerves fire and tellyour spinal cord that something is wrong. The spinal cord takes this message tothe brain to decide how badly you’re hurt and what to do now. Based on your pastexperiences, your brain will pick from endless possible responses and decide tomake your body cry, increase your heart rate, or release adrenaline.


The severity of the pain will lessen with time. When yourinjury has healed or is mostly better, the acute pain will subside. 

Chronic Pain

Chronic pain is different from acute pain and is defined aspain that lasts for three months or more (or longer than the expected healingtime). In this case, your pain receptors continue to fire even when you are notdirectly injured.


Diseases and other conditions that damage your body can resultin chronic pain, as can old injuries. But sometimes, even doctors can’t pindown the cause. Some common examples include:

  • Arthritis
  • Fibromyalgia
  • Cancer
  • Sclerosis
  • Poor posture
  • Improper lifting technique
  • Being overweight

From your memories and past experiences to yourcurrent social and psychological state, almost anything can contribute to howyou feel pain.
