This depends on the specific “pain point.” Epileptic injection (ESI): More direct for precise nerve root compression (such as radiating pain in the leg caused by a herniated disc). ESP block: More advantageous for large-area back pain, intercostal pain, and postoperative recovery. It is recommended that you have an evaluation by a dual-specialist team at Jianli Clinic to develop the most precise repair plan.
Highly effective. Postherpetic neuralgia often causes patients to experience excruciating pain, like electric shocks or burning. ESP Block can cover a large area of the affected ganglia, effectively reducing nerve inflammation and abnormal discharges. Many patients have experienced significant improvements in sleep quality and daily life after receiving ESP Block.
After treatment, observe for 15–30 minutes. If there is no dizziness or discomfort, you can go home. Although most patients can move immediately, some patients may experience temporary muscle weakness. It is recommended to avoid strenuous exercise or long-distance driving on the same day.
* Immediate Effects: Approximately 15-30 minutes after injection, the local anesthetic takes effect, and you will feel significant relief. Duration: The duration of the effect varies from person to person. Local anesthesia alone lasts from several hours to several days; if combined with steroids or regenerative medicine therapies (such as PRP), the pain relief and repair effects can be extended to 1-2 weeks or even longer.
This is precisely where ESP Block excels! For patients taking anticoagulants who are not suitable for deep epidural injections, ESP Block is currently recognized in medicine as a very safe and ideal alternative because of its superficial injection site and distance from major blood vessels.
General anesthesia is not required. The procedure is similar to a regular injection, with the doctor administering local anesthesia first. Because the entire treatment is guided by ultrasound, the doctor can see the needle tip in real time and avoid important tissues, so the process usually only causes a slight soreness and takes about 20–30 minutes to complete.
Rest assured, it will not enter the spinal canal. This is the biggest advantage of ESP Block! It is injected into the deep plane of the erector spinae muscles, far from the spinal cord and major blood vessels, making it a highly precise, non-invasive injection. Compared to traditional epidural injections, the risk of complications is extremely low, and safety is significantly improved.
You can think of it as a “nerve circuit breaker” for body pain. Doctors use ultrasound to precisely locate the deep fascia layer next to the spine and inject medication into this “nerve conduction highway.” The medication spreads widely along the fascia, like a “pain-relieving rain” falling on the painful area, blocking pain signals in multiple segments.
Red flag symptoms requiring immediate return to the doctor or emergency room: Fever, worsening redness, swelling, heat, and pain at the injection site Progressive weakness or numbness in the lower extremities Incontinence (urinary or fecal incontinence) Severe headache (relieved by lying down, worsened by sitting up; may be a puncture headache) Abnormal bleeding, large bruising Severely uncontrolled blood sugar or blood pressure
