Cutaneous nerve entrapment is a common yet often underdiagnosed cause of localized pain, numbness, or paresthesia. It occurs when a superficial nerve becomes compressed or irritated by surrounding tissues such as fascia, scar tissue, or anatomical variations. This condition can significantly impact quality of life if not properly addressed. One of the most effective treatment strategies for managing cutaneous nerve entrapment is the use of nerve blocks, which provide targeted anesthesia and can also serve as diagnostic tools.

Nerve blocks involve the injection of local anesthetics around a specific nerve or nerve branch to interrupt nerve conduction temporarily. Their primary goals are symptom relief and confirmation of the nerve as the pain source. When accurately administered, nerve blocks can reduce inflammation, relax surrounding tissues, and improve patient comfort, often providing immediate relief. This also helps clinicians confirm the diagnosis, guiding further treatment options such as physical therapy, medication, or surgical intervention.

The first step is thorough clinical assessment and identification of the affected nerve based on the patient’s symptoms and distribution of pain. Ultrasound guidance has become increasingly favored for nerve blocks because it allows real-time visualization of nerve structures, surrounding tissues, and the needle, resulting in higher accuracy and safety. Palpation and anatomical landmarks are also utilized, especially in settings where ultrasound may not be available.
In performing a nerve block, the clinician injects a local anesthetic—commonly lidocaine, bupivacaine, or ropivacaine—directly around the nerve. For cutaneous nerves, this often involves small, superficial injections along the nerve pathway. The volume and concentration of anesthetic are carefully chosen to maximize efficacy while minimizing systemic absorption and potential toxicity. Sometimes, a corticosteroid may be added to prolong the duration of relief and reduce inflammation.

Specific nerves frequently targeted include the lateral femoral cutaneous nerve, ilioinguinal nerve, genitofemoral nerve, and superficial branches of the trigeminal nerve, depending on the site of entrapment. For example, in meralgia paresthetica, the lateral femoral cutaneous nerve is often involved, and a well-executed nerve block can provide significant symptomatic relief.
While nerve blocks are generally safe, potential complications include infection, bleeding, nerve injury, allergic reactions, and transient nerve palsy. Proper technique, sterile precautions, and patient monitoring are essential. Repeated blocks may be performed if needed, but if relief is temporary or if nerve damage is suspected, surgical decompression could be considered.

In conclusion, effective nerve blocks are an invaluable tool in managing cutaneous nerve entrapment. They offer diagnostic clarity, immediate symptom relief, and can serve as a bridge to definitive treatment. The success of such interventions depends on a detailed understanding of nerve anatomy, careful technique, and appropriate patient selection, ultimately improving patient outcomes and quality of life.
