S1 Selective Nerve Root Block for Sciatica and Back Pain in Kolkata

Low back pain associated with radiating leg pain, commonly known as sciatica, is one of the most frequent reasons for patients seeking medical consultation. In many cases, the pain originates from irritation or compression of a specific spinal nerve, most commonly the S1 nerve root. When medications, physiotherapy, and lifestyle modification fail to provide adequate relief, S1 Selective Nerve Root Block becomes an effective and minimally invasive treatment option.

At Samobathi Pain Clinic, Kolkata, S1 selective nerve root block is performed using advanced imaging guidance to provide precise, targeted pain relief, helping patients return to normal life without the need for surgery.

What Is S1 Selective Nerve Root Block?

S1 Selective Nerve Root Block for back pain in Kolkata is a specialized injection technique in which anti-inflammatory medication combined with a local anesthetic is delivered directly around the S1 spinal nerve root. The S1 nerve supplies sensation and motor control to the back of the thigh, calf, heel, and sole of the foot. When this nerve becomes inflamed or compressed, patients experience classical sciatica symptoms such as sharp shooting pain, burning sensation, tingling, numbness, and sometimes weakness in the lower limb.

The purpose of a selective nerve root block is twofold. First, it provides therapeutic pain relief by reducing inflammation around the nerve. Second, it serves as a diagnostic tool, helping confirm whether the S1 nerve root is truly responsible for the patient’s symptoms.

Unlike routine epidural injections, selective nerve root blocks target only one specific nerve, allowing precise treatment with minimal medication spread.

When Is S1 Selective Nerve Root Block Recommended?

S1 Selective Nerve Root Block for sciatica and back pain in Kolkata is recommended when patients suffer from persistent leg pain radiating below the knee, particularly along the calf and foot, which does not respond adequately to conservative treatment. It is especially helpful in conditions such as lumbar disc prolapse at L5–S1, foraminal stenosis, degenerative disc disease, spinal canal narrowing, and post-surgical nerve irritation.

Patients often present with difficulty sitting for long periods, pain while standing or walking, disturbed sleep, and reduced quality of life. When imaging findings correlate with clinical symptoms, S1 selective nerve root block offers a safe and effective non-surgical solution.

At Samobathi Pain Clinic, careful clinical assessment, neurological examination, and MRI correlation are done before recommending this procedure.

How Does S1 Selective Nerve Root Block Work?

The success of S1 Selective Nerve Root Block for back pain in Kolkata lies in its precise mechanism of action. Most radicular pain is caused by inflammation around the compressed nerve root. Oral medications often fail to reach this inflamed area in sufficient concentration.

By placing the medication directly next to the S1 nerve, the steroid rapidly reduces inflammation and swelling, relieving pressure on the nerve. The local anesthetic provides immediate pain relief, while the steroid offers sustained benefit over weeks to months. This dual action allows faster recovery, improved mobility, and better participation in rehabilitation therapy.

How Is the Procedure Performed at Samobathi Pain Clinic?

At Samobathi Pain Clinic, S1 Selective Nerve Root Block in Kolkata is performed as a short daycare procedure under strict sterile precautions. The patient is positioned comfortably, and the skin is thoroughly disinfected. Using real-time fluoroscopic imaging, a fine needle is carefully guided to the S1 nerve root through the natural bony opening known as the neural foramen.

Contrast dye is injected to confirm precise needle placement. Once correct positioning is ensured, a small volume of steroid and local anesthetic is administered. The entire procedure usually takes about 15 to 20 minutes. Patients are observed for a short period afterward and can usually return home the same day.

Most patients can resume routine daily activities within 24 hours.

One of the major advantages of S1 Selective Nerve Root Block for sciatica and back pain in Kolkata is rapid symptom relief without surgery. Patients often notice significant reduction in leg pain, improvement in walking tolerance, better posture, and improved sleep.

By reducing nerve inflammation early, the procedure helps prevent chronic pain development and long-term nerve damage. It also allows patients to actively participate in physiotherapy, which is essential for long-term spinal health. In many cases, selective nerve root block helps delay or completely avoid spinal surgery.

Is S1 Selective Nerve Root Block Safe?

When performed under imaging guidance by trained pain specialists, S1 Selective Nerve Root Block in Kolkata is a very safe procedure. Mild soreness at the injection site or temporary numbness in the leg may occur, but serious complications are extremely rare.
