What is Meralgia Paresthetica?
Meralgia paresthetica is a disorder characterized by tingling, numbness, and burning pain in the outer side of the thigh.
The disorder is caused by compression of the lateral femoral cutaneous nerve, a sensory nerve to the skin, as it exits the
pelvis. People with the disorder often notice a patch of skin that is sensitive to touch and sometimes painful. Meralgia paresthetica
should not be associated with weakness or radiating pain from the back.
Is there any treatment?
Treatment for meralgia paresthetica is symptomatic and supportive. The majority of cases improve with conservative treatment
by wearing looser clothing and losing weight. Medications used to treat neurogenic pain, such as anti-seizure or anti-depressant
medications, may alleviate symptoms of pain. In a few cases, in which pain is persistent or severe, surgical intervention
may be indicated.
What is the prognosis?
Meralgia paresthetica usually has a good prognosis. In most cases, meralgia paresthetica will improve with conservative treatment
or may even spontaneously resolve. Surgical intervention is not always fully successful.
What research is being done?
Within the NINDS research programs, meralgia paresthetica is addressed primarily through studies associated with pain research.
NINDS vigorously pursues a research program seeking new treatments for pain and nerve damage with the ultimate goal of reversing
these debilitating conditions.
