The causes of meralgia paresthetica are quite diverse. When the lateral femoral cutaneous nerve (LFCN) is squeezed, swollen, or damaged it causes pain or numbness (loss of feeling) in your thigh. Caregivers may not know exactly what caused your MP. Causes may include the following:
1. Medical Causes of Meralgia Paresthetica:
- Leprosy (skin disease)
- Fluid buildup in the abdomen can cause MP
- Acquired immunodeficiency syndrome (AIDS).
- Hip or knee arthritis
- Back pain
- Pregnancy or growths in your uterus
- Lead poisoning
- Too much alcohol, too often.
- Growths in organs that are near your LFCN
- One leg that is longer than the other
- Tight clothing, belts, leg braces all put pressure on your LFCN
- Trauma: Surface or deep injuries to your thigh or groin area may cause MP.
- Growth of bones in soft tissue after an injury may also lead to MP.
2. Anti-rejection medicine: Anti-rejection medicine is given after an organ transplant. This medicine helps stop your body from rejecting the new organ. This medicine may cause MP.
