Causes

One of the reasons Intercostal Neuralgia (I. N.) is difficult for physicians to diagnose is that the symptom can be caused by a wide variety of reasons that can range from mild to serious. These reasons include infections, inflammations, traumas, malignancy, and other abnormal medical conditions.

The pain associated with I. N. can be constant and life altering and it may involve any of the intercostal nerves. It may also affect the subcostal nerve of the twelfth rib. If the subcostal nerve is involved, gallbladder disease may be suspected.

Two of the more common causes of I. N. are surgery that involves the thoracic (Chest) cavity and Shingles (Herpes Zoster).

Surgery related causes typically result from spreading apart the ribs or the intercostal nerves becoming damaged during the procedure. Post-operational pain affecting the intercostal areas that become chronic may be a sign of I. N.

Shingles can affect the ribcage area of the body and wrap around the torso. Left untreated, the herpes zoster virus can cause damage to the intercostal nerves. In rare cases, a patient can contract shingles that do not represent the blistering commonly associated with the virus.

Here is a list of possible causes of Intercostal Neuralgia to consider when seeking a diagnosis:

• Shingles (herpes zoster)
• Falls (trauma to ribs)
• Athletic activities
• Prolonged, violent coughing
• Surgical operations which pin the patient in certain positions for prolonged period
• Osteoporosis with vertebral collapse
• Degenerative thoracic disks
• Painful neuropathies
• Rib-joint arthritis
• Spine deformities such as scoliosis
• Certain intra-thoracic tumors
• Obesity
• Pregnancy

Basically any condition or event that can compress, irritate, or damage the intercostal and thoracic nerves, can lead to a patient suffering Intercostal Neuralgia.

*NOTE* The above mentioned are “possible” causes. Please seek professional help from your physician if you believe you may be suffering from Intercostal Neuralgia as other possible life threatening ailments can mimic the symptoms of I. N.
