Causes of Pain

We all know there are different types of pain and of course, there are also different causes of pain.

Usually, pain is the mechanism our body has to prevent us from injury or as a warning that something is not working fine in our body, is a signal from our nervous system that goes up the spinal cord to our brain.

Most common or known causes of pain

We have different ways to describe it, sometimes like stabbing, cramps or burnings. And there are also many known types of pain, same as causes of pain, here we describe the top common causes of pain.


The International Headache Society (IHS) categorize headache as primary when they are not caused by another condition, or secondary when there is a further underlying cause.

  • Primary headaches can be cluster headaches and tension headaches.
  • Secondary headaches work as a symptom of another cause which could be: hangover, blood clots, concussion, “ brain freeze” and so on.


It is under the definition of primary headaches and is usually described as throbbing pain or stab. This can goes from moderate to severe and affect our vision, feel nausea or extreme light or sound sensitivity.

Post-surgical pain

Post-surgical pain can often be treated easily and can be felt like mmusclespasm after having a cesarean section, abdominal or heart surgery or hernia repair. In fact, it is normal after a procedure to feel pain and the surgeon can even tell you that is good. A treatment for post-surgical pain is always done before an operation and can vary after the procedure and the pain intensity.

Post-trauma pain

Post-trauma pain often appears after an accident or sports injury. This affects the nerve directly or traumatized tissues near nerves. Pain could remain during the recovery process and disappear after healing or in worst cases develop into Chronic pain.

Lower back pain

Lower back pain is related to our spine health. Is like the most known or common pain but very complex at the same time. Any problem or injury with bones, nerves, spinal muscles tendons or discs can develop in lower back pain. There are as many types of treatment as pains and intensity.

Cancer pain

Cancer pain is usually originated when a tumor is pressing bones, organs or nerves and it can also be a result of cancer treatments like radiotherapy, chemotherapy. It can start as acute pain and develop into long-lasting pain but there is always a pain management plan along with your cancer treatment.


Injury pain is likely the “easiest” one as it appears as a normal response of our body from being hurt or damage by an external factor. Such as knife, weapons or accident.

Arthritis pain

Arthritis pain is directly related to joint pain. Is the inflammation process of one or more joints. Most pain treatments are based on anti-inflammatory drugs and exercise for mobility improvement and better quality of life.


Osteoarthritis is an arthritis type and affects the cartilage of joint bones, they start to rub each other and change shape mostly it could lead to disability as this affects the knees and hips joint. Therapy goes from losing weight and exercise to painkillers and anti-inflammatory medication.

Multiple sclerosis

Multiple sclerosis pain may vary from musculoskeletal pain (damage tendons, ligaments, muscles) to neuropathic pain (damage to the spinal cord and brain nerves).
Neuropathic pain in MS includes numbness, burning feelings, or painful sensations in one side of the face.


Fibromyalgia pain can be similar to Osteoarthritis pain, it can start in one specific area and then evolves to the entire body. It is described as a deep sharp pain starting with tingling in hand, arms feet or legs and could ended up into sleeping problems, fatigue or depression.


Shingles pain is quite unknown but is a postherpetic neuralgia result of shingles (varicella-zoster virus). This develops into a painful rush because of the skin nerves damaged.
Shingles pain could be felt as burnings and sharp stabbings but it should not last more than a couple of weeks.

Nerve damage (neuropathy or neurogenic pain)

Neuropathic pain is associated with an injured or diseased nerve and is related to chronic pain condition. How our body works is regulated by our nervous system and when nerves are damage we have problems controlling muscles and our senses. Losing this develops, in sensory nerve damage that goes from numbness to severe pain.

Muscle pain

Muscle pain could be localized pain that only affects a part of our body or a couple of muscles. For example muscle cramp, sprains and strains or hypothyroidism.
Systemic muscle pain affects the entire body and could be as an infection or virus result like flu or lupus.

Stomach or abdominal pain

Stomach or abdominal pain can vary in intensity and indicates different things. Symptoms like indigestion, gas, constipation or bloating they can be treated easily and disappears fast.
But, persist or severe abdominal pain is due inflammation of an abdominal organ ( pancreas, colon, stomach, liver, gallbladder, spleen, small intestine) and indicates serious illness (appendicitis, gallstones, hepatitis, obstruction of the intestine and many others)

Ear pain

Ear pain is usually associated with children but it also affects adults. We can easily distinguish air pain due to air pressure, earwax, ear infection or swimmer’s ear or otitis. Treatment is normally based on painkillers and appropriate antibiotics.

Testicular pain

Testicular pain may vary from short to long duration and affect one or both testicles. As this is a very sensitive part of the body any injury can cause pain. Usually indicates infection or inflammation of the prostate, inguinal hernia, testicular torsion or others.

Pelvic pain

Pelvic pain, usually associated with women’s internal reproductive organs.
Three common gynecologic conditions that could cause Pelvic (lower abdomen) pain are ovarian cysts, uterine fibroids, and endometriosis. once the pain cause has been identified your doctor will give you an accurate treatment.

Heel pain

Heel pain could be also known as Plantar fasciitis and is an inflammation of the plantar fascia, pain is located under the foot, towards the front of the heel and it differs if arches are too high or too low. Usually takes nonsurgical treatment.

You must remember that all causes of pain can vary according to each person and that a doctor must always be consulted for an accurate pain treatment.
