What are the worst medical pains that humans can suffer?

Pain threshold can vary from person to person, but there are some medical conditions suffered by humans that are so painfully excruciating that they can bring even the toughest to their knees. We are not talking about a bruised elbow or a stubbed toe. Instead, these are serious health-related issues that induce acute pain and distress, with some potentially fatal in their diagnosis.

So, just how unbearable is the unbearable? Click through and examine this list of painful disorders.

Toothache

One of the most common ailments we can experience, a throbbing toothache can be unbearably painful. And if not treated promptly, toothache can migrate to your jaw or even the side of your face.

Renal colic

One stage further, renal colic can also be acutely painful. It occurs when a kidney stone or other crystalized substance gets stuck in the urinary tract. Many people describe it as the worst pain they've ever felt in their life.

Heart attack

A heart attack or myocardial infarction is a potentially fatal condition in which a part of the heart loses its blood supply. A mild attack manifests itself as a sensation of uncomfortable pressure, a feeling of squeezing or fullness of the chest. An acute episode brings with it a crushing chest pain usually coupled with overwhelming nausea. In either case, immediate medical attention is critical.

Endometriosis

Endometriosis occurs when tissue similar to the lining of the uterus grows outside of the womb. The condition can also affect the fallopian tubes, ovaries, and the tissue lining the pelvis. The result is severe and disabling pain.

Peripheral neuropathy

Peripheral neuropathy develops when nerves in the body's extremities, such as the hands, feet, and arms, are damaged. This malfunction, commonly caused by diabetes, also affects signaling between hands and feet. The resulting pain, numbness, and tingling can be very distressing.

Fibromyalgia

Widespread, seemingly never-ending musculoskeletal pain is the result of fibromyalgia. While the causes of fibromyalgia are not yet fully understood, the condition also brings with it fatigue, sleep, memory, and mood issues.

Trigeminal neuralgia

Sudden severe facial pain can be indicative of trigeminal neuralgia, a medical condition that's been described as akin to experiencing an electric shock in the jaw, teeth, or gums. In most cases, trigeminal neuralgia affects just one side of the face, with the pain usually felt in the lower part of the face.

Interstitial cystitis

Another way of describing an inflamed and overly sensitive bladder, interstitial cystitis induces a nasty burning sensation in the pelvic area and an incessant need to urinate.

Intracranial hypertension

Intracranial hypertension is a potentially serious medical condition brought on when the pressure of the fluid that surrounds the brain is too high. This in turn induces sudden and severe headache. If left untreated, intracranial hypertension can result in permanent visual issues or blindness.

Dercum's disease

So painful are the effects of Dercum's disease that even taking a shower is an excruciating experience. The condition is characterized by multiple painful growths of fatty tissue, or lipomas, that cluster under the skin making affected areas extremely tender and painful to the touch.

Complex regional pain syndrome

This disorder is broadly underscored by uncontrolled behavior in the pain receptors, which usually occurs after a person has suffered traumatic nerve damage as a result from injury to an arm or leg. The affected limb is often extremely sensitive to touch, a sensation characterized by a burning, stabbing, stinging, or throbbing pain.

Peritonitis

Peritonitis is an infection of the inner lining of the abdomen that causes acute redness and swelling of the peritoneum. First symptoms include a dull ache in the belly that quickly turns into persistent, severe abdominal pain.

Frozen shoulder

Frozen shoulder is exactly that—stiffness in the shoulder that eventually results in the joint becoming very hard to move. The accompanying pain is a result of the inflammation associated with this disorder, which is also known as adhesive capsulitis.

Stomach ulcer

By their very nature, gastric ulcers— open sores on the lining of your stomach or small intestine—are intensely painful and debilitating. Stomach pain is the most obvious symptom of an ulcer, discomfort that may occur briefly or last for hours.

Emotional pain

Never underestimate the effect of emotional pain on the human condition. Emotional distress can induce physical as well as mental pain, the condition having a tendency to cause symptoms of pain throughout the body.
