Meralgia Paresthetica: When The Thigh Burns
Meralgia paresthetica (MP) or femoral nerve sensory neuropathy (NFC) is a relatively common disease, especially in pregnant women or men who have gained weight.
The MP is manifested by burning or tingling sensation unpleasant side or the outer thigh, never below the knee. This discomfort can be permanent and may worsen at night or when you are calmer, and although not disabling, can become very annoying.
The NFC is born of the union of several roots arising from the lumbar spine (L2L3) and running through the abdomen and pelvis from the most dorsal up to the groin, where does the NFC and its branches is given to the sensitivities of the lateral or outer thigh.
The NFC may be compressed by the uterus during pregnancy, especially in more advanced stages of pregnancy. Sometimes, in people who have risen sharply in weight, the NFC is compressed in its output in the groin, l which can also cause the symptoms of MP.
In many cases simply not managed to determine the cause of the MP, it will normally take about 3-6 months and then gradually disappear.
In some particular cases it is necessary to deepen the study with lower limb electromyography (nerve roots and to explore them one by one), CT or MRI of abdomen and pelvis to look for tumors that can compress the NFC in the trajectory and MRI of the lumbar spine when wants to rule out pathology column that can simulate a MP.
The treatment for pregnant women is waiting for delivery, after which symptoms usually improved completely. In overweight, lose weight, and the symptoms, drugs such as carbamazepine, amitriptyline, gabapentin, pregabalin, oxcarbazepine, Duloxetine, etc.
