Understanding Meralgia Paresthetica: Causes and Symptoms

Individuals experiencing pain, numbness, tingling, or a burning sensation in the front and outer thigh could have meralgia paresthetica, a nerve entrapment. Can understanding the condition help healthcare providers develop an effective treatment plan?

Meralgia Paresthetica

Meralgia paresthetica, or MP, is also known as Bernhardt-Roth syndrome, lateral femoral cutaneous nerve syndrome, or lateral femoral cutaneous neuralgia. It occurs when the lateral femoral cutaneous nerve, a sensory nerve that passes over the brim of the pelvis and down the front of the thigh, becomes compressed. The nerve supplies information about sensations over the front and outside of the thigh. This can happen for several reasons, including:

• Recent hip injuries, such as from a motor vehicle collision/accident.
• Repetitive hip activities, like cycling.
• Pregnancy
• Weight gain
• Wearing tight clothing.

The nerve entrapment condition causes tingling, numbness, and burning pain in the front and/or outer thigh.

Causes

There can be several different causes of this condition, but it is frequently seen in pregnancy, sudden weight gain, wearing tight clothing or belts, and other conditions. (Ivins G. K. 2000) Sometimes, meralgia paresthetica can be caused by medical procedures. For example, the condition can present after an individual has surgery and is in an unusual position for a long period of time, where there is direct external pressure on the nerve. Also, the nerve can become damaged during a surgical procedure. (Cheatham S. W. et al., 2013) This can occur when a bone graft is obtained from the pelvis or anterior hip replacement surgery.

Symptoms

Individuals may experience some or all of the following symptoms (Chung K. H. et al., 2010)

• Numbness over the outside of the thigh.
• Pain or burning on the outside of the thigh.
• Sensitivity to lightly touching the outside of the thigh.
• Worsening of symptoms with certain positions.
• Increased symptoms when wearing belts, work belts, or tight-waist clothes.

The symptoms may come and go or be persistent. Some individuals are hardly noticeable and do not impact their lives or activities, while others can be very bothersome and cause significant pain. (Scholz C. et al., 2023)

Treatment

Treatment depends on how long the injury has been present and the frequency and severity of the condition.

Clothing Modifications

If the cause is due to tight clothing, belts, or work belts, then garment modification should alleviate symptoms.

Pregnancy

Pregnant women usually find complete relief of their symptoms after delivery. (Hosley, C. M., and McCullough, L. D. 2011)

Weight Loss Program

If recent weight gain is thought to contribute to the condition, then a weight loss program may be recommended.

Cortisone Injections

If simple steps do not relieve symptoms, a cortisone injection around the nerve area may be recommended. The goal is to reduce inflammation that contributes to nerve pressure (Houle S. 2012). Cortisone injections may be a definitive treatment or a temporary treatment.

Chiropractic

Chiropractic care can be an effective, natural, and safe treatment. Adjustments can help relieve pressure on the lateral femoral cutaneous nerve (LFCN) by realigning the spine and restoring nerve function. Chiropractors may also use soft tissue therapies, such as massage, to relieve muscle tension and support the body’s healing process. Other chiropractic techniques that may be used include:

• Pelvic mobilizations
• Myofascial therapy
• Transverse friction massage
• Stretching exercises
• Stabilization exercises for the core and pelvis
• Therapeutic kinesiology tape

A chiropractic treatment program may include 10–15 treatments over 6–8 weeks, but the number of treatments needed will vary from person to person. If there’s no noticeable progress after 3–4 weeks, it may be time to consult a specialist or surgeon.

Surgery

Surgery is rarely necessary. However, a surgical procedure may be considered when all conservative treatments fail to provide relief. (Schwaiger K. et al., 2018) A surgeon dissects and identifies the nerve, looks for compression locations, and tries to free the nerve from any areas where it may be pinched. Alternatively, some surgeons transect/cut the nerve so it no longer causes problems. If the transection procedure is performed, there will be a permanent area of numbness over the front of the thigh.

Injury Medical Chiropractic and Functional Medicine Clinic works with primary healthcare providers and specialists to develop a customized treatment plan to relieve pain, treat injuries, improve flexibility, mobility, and agility, and help individuals return to optimal function. If other treatments are needed, Dr. Jimenez has teamed up with top surgeons, clinical specialists, medical researchers, and rehabilitation providers to provide the most effective treatments.
