In addition to the previous pain conditions described which are most common, there is a myriad of other pain conditions affecting different parts of body with specific causes and treatments.

A. Facial Pain

Facial pain refers to pain felt in any region of the face that may develop suddenly or gradually, ranging anywhere from dull aches to sharp jabs or burning sensations. Facial pain is usually immediately obvious to a person and usually immediately disruptive of whatever activity that person is doing.

Pain in the facial area may be due to neurological, vascular causes or due to infections affecting nerves, blood vessels, muscles, or dental tissues.


Complex Regional Pain Syndrome is a chronic pain condition that most often affects one limb (arm, leg, hand, or foot) usually after a crushing injury, fracture or amputation. It is believed to be caused by damage to, or malfunction of, the peripheral and central nervous systems.

CRPS symptoms vary in severity and duration, although some cases are mild and eventually go away. In more severe cases, individuals may not recover and may have long-term disability.

CRPS is characterized by prolonged or excessive pain and changes in skin color, temperature, and/or swelling in the affected area. It has been described as “burning,” “pins and needles” sensation, or as if someone were squeezing the affected limb. The pain may spread to the entire arm or leg, even though the injury might have only involved a finger or toe. In rare cases, pain can sometimes even travel to the opposite extremity. There is often increased sensitivity in the affected area.

C. Abdominal Pain

Abdominal pain is pain felt anywhere from below the ribs to the pelvis. The abdomen houses many organs, including the stomach, liver, pancreas, small and large bowel, and the reproductive organs. There are also major blood vessels in the abdomen. Problems with any of these organs or structures can cause pain.

Serious causes of abdominal pain that need intervention include appendicitis, an abdominal aortic aneurysm, a bowel blockage, cancer, and gastroesophageal reflux.

D. Pelvic Pain

Pelvic pain is a symptom that affects many women and is felt in the lower abdomen, pelvis, or perineum. It might stem from infections, abnormalities in internal organs, or pain from the pelvic bones. Conditions that may result in pelvic pain can range from endometriosis or fibroids to more serious ones, like an ectopic pregnancy or cancer.

Women typically describe it as a dull ache or pressure that may or may not include sharp pains located anywhere in the abdomen below the navel. The pain may be intermittent or constant and can be accompanied by other symptoms, such as lower back pain and pain in the groin and urogenital organs.

E. Knee and Hip Pain

Hip and knee are large joints and have a demanding task of bearing the weight of our body while allowing a wide range of motion. Wear and tear, injury, arthritis or repetitive strain can cause pain in them.

Severe knee pain can occur in people of all ages for a range of reasons. Symptoms of knee injury can include pain, swelling, and stiffness.

Hip disorders often produce a limp, a reduced walking distance, and stiffness that prevents activities of daily living, such as getting in and out of baths, putting on shoes, and foot care.

F. Neuropathic Pain

Neuropathic pain is caused by damage or injury to the nerves that transfer information between the brain and spinal cord from the skin, muscles and other parts of the body.

The pain is usually described as a burning sensation and affected areas are often sensitive to the touch. Symptoms of neuropathic pain may also include excruciating pain, pins and needles, difficulty correctly sensing temperatures and numbness.

Common causes of neuropathic pain include nerve pressure or nerve damage after surgery or trauma, viral infections, cancer, vascular malformations, alcoholism, neurological conditions such as multiple sclerosis and metabolic conditions such as diabetes. It may also be a side effect of certain medications or chemotherapy.

G. Nociceptive Pain

Nociceptive pain is a medical term used to describe the pain from physical damage or potential damage to the body. It develops when the nociceptive nerve fibers are triggered by inflammation, chemicals, or physical events.

Nociceptive pain is usually acute and develops in response to a specific situation. It tends to go away as the affected body part heals.
