What is meralgia paresthetica?
- Meralgia paresthetica is an entrapment or "pinching" of the nerve that supplies sensation to the outer portion of the thigh.
- The lateral femoral cutaneous nerve becomes "entrapped" as it passes under the ligament of the groin.
- The pressure on the nerve causes abnormal sensations of burning, pain, and numbness in the distribution of this nerve, the outer and part of the front of the thigh.
- Meralgia paresthetica is also known as lateral femoral cutaneous nerve syndrome.
What causes meralgia paresthetica?
Causes of meralgia paresthetica include any condition that leads to an increase in pressure on the groin (usually associated with enlargement of the belly, such as in obesity or pregnancy).
What is the treatment for meralgia paresthetica?
The treatment of meralgia paresthetica usually involves addressing the underlying cause. Meralgia paresthetica can also be treated by local cortisone injection at the point where the nerve crosses the crease in the groin. Medications commonly utilized in the treatment of neuropathic pain, such as gabapentin, may be used. Infrequently, surgical release of the nerve is necessary.

Cortisone Injection
Cortisone injections are used to treat small areas of inflammation or widespread inflammation throughout the body. There is minimal pain from these injections, and relief from the pain of inflammation occurs rapidly.
Obesity (Weight Loss)
Obesity is the state of being well above one's normal weight. A person has traditionally been considered to be obese if they are more than 20% over their ideal weight. That ideal weight must take into account the person's height, age, sex, and build.
Peripheral Neuropathy
Peripheral neuropathy is a problem with the functioning of the nerves outside of the spinal cord. Symptoms may include numbness, weakness, burning pain (especially at night), and loss of reflexes. Possible causes may include carpel tunnel syndrome, shingles, vitamin or nutritional deficiencies, and illnesses like diabetes, syphilis, AIDS, and kidney failure. Peripheral neuropathy is diagnosed with exams and tests. Treatment for the condition depends on the cause. Usually, the prognosis for peripheral neuropathy is good if the cause can be successfully treated or prevented.
Pinched Nerve Overview
A pinched nerve causes pain, numbness, or tingling in the affected area due to pressure on a nerve. Caral tunnel and sciatica are two examples of conditions caused by a pinched nerve. A pinched nerve is diagnosed by taking a patient history and performing a physical examination. Electromyography may be performed. Treatment for a pinched nerve depends on the underlying cause.
