Chronic Pain Management: Nerve Blocks, Intrathecal Drug Delivery, and Estimated Costs in Kenya
Living with chronic pain is exhausting. Whether it stems from a damaged nerve, a spine condition, cancer, or a long-term injury, persistent pain affects every part of daily life. The good news is that Kenya’s pain management landscape has grown significantly. Specialist clinics in Nairobi and major referral hospitals now offer advanced interventional procedures that can dramatically reduce pain — or eliminate it entirely.
This article explains the most important chronic pain procedures available in Kenya, what each one does, and what you can expect to pay in 2025.
What Is Interventional Pain Management?
Interventional pain management uses minimally invasive procedures to interrupt, block, or manage pain signals before they reach the brain. Unlike oral painkillers, which affect the whole body, these techniques target the specific nerve or region causing the problem. This means better pain relief with fewer side effects and less dependence on strong medications such as opioids.
Estimated Costs of Chronic Pain Procedures in Kenya (2025)
Note: Costs vary by facility, specialist, imaging guidance used (fluoroscopy or ultrasound), and number of injections. These figures are market estimates. Always request a written quote from your provider.

Key facilities offering interventional pain services in Kenya include Nairobi Hospital, Aga Khan University Hospital, MP Shah Hospital, Karen Hospital, Kenyatta National Hospital (KNH) pain clinic, and Moi Teaching and Referral Hospital (MTRH).
1. Nerve Blocks
What they are: A nerve block is an injection of local anaesthetic, steroid, or a combination of both, delivered precisely around a targeted nerve or group of nerves.
Why they are done: Nerve blocks serve two purposes. A diagnostic block confirms which nerve is responsible for the pain. A therapeutic block relieves pain, sometimes for weeks or months at a time. They are used for conditions including sciatica, herniated discs, post-surgical pain, cancer pain, and complex regional pain syndrome (CRPS).
Common types available in Kenya:
- Epidural steroid injection — targets inflamed nerves in the spine, most often used for lower back and leg pain caused by disc herniation or spinal stenosis
- Facet joint injection — treats arthritic joint pain in the cervical (neck) or lumbar (lower back) spine
- Sympathetic nerve block — interrupts pain signals from the sympathetic nervous system, used for CRPS and vascular pain
- Coeliac plexus block — targets the nerve cluster supplying the upper abdominal organs; particularly effective for pancreatic cancer pain
- Trigger point injection — relieves tight, painful muscle knots (trigger points) in the neck, shoulders, and lower back
What to expect: Most injections are done under X-ray (fluoroscopy) or ultrasound guidance to ensure accuracy. The procedure takes 15 to 30 minutes. You may feel mild soreness at the injection site for one to two days. Pain relief can begin within 24 to 72 hours and may last from a few weeks to several months depending on the type of block.
2. Radiofrequency Ablation (RFA)
What it is: Radiofrequency ablation uses heat generated by radio waves to damage — or “ablate” — specific nerve fibres that are transmitting pain signals.
Why it is done: RFA offers longer-lasting pain relief than steroid injections. It is most commonly used for chronic facet joint pain in the neck and lower back after steroid injections have confirmed which nerves are responsible.
What to expect: The procedure takes 30 to 60 minutes under light sedation. A thin needle electrode is guided to the target nerve using fluoroscopy. A small area of nerve tissue is heated to around 80°C, interrupting the pain signal. Relief typically lasts six to 18 months, after which the nerves may regenerate and the procedure can be repeated.
3. Intrathecal Drug Delivery (Pain Pump)
What it is: Intrathecal drug delivery is one of the most advanced pain interventions available. A small programmable pump is surgically implanted under the skin of the abdomen. It delivers pain medication — most commonly morphine or baclofen — directly into the intrathecal space surrounding the spinal cord.
Why it is done: Delivering medication directly to the spinal fluid means the drug works at a fraction of the oral dose. This provides far more effective pain control with dramatically fewer systemic side effects such as nausea, sedation, and constipation.
Who benefits most: Patients with cancer pain uncontrolled by oral opioids, severe spasticity from spinal cord injury or multiple sclerosis, and people with failed back surgery syndrome are the strongest candidates.
The trial phase: Before implanting a permanent pump, your pain specialist will perform a trial. Medication is delivered through a temporary catheter for a few days while your pain response is carefully monitored. A permanent pump is only implanted if the trial demonstrates meaningful benefit.
What to expect after implantation: The pump is refilled by a specialist every one to three months using a needle inserted through the skin. The device is reprogrammed wirelessly to adjust dosing as your needs change. Battery life is typically five to seven years, after which the device is replaced. The system is fully reversible — it can be removed at any time.
4. Spinal Cord Stimulation (SCS)
What it is: Spinal cord stimulation delivers mild electrical pulses to the spinal cord through thin electrodes implanted in the epidural space. The electrical signals modify how pain messages travel to the brain — replacing the sensation of pain with a mild tingling or, in newer systems, no sensation at all.
Why it is done: SCS is used for chronic pain that has not responded to surgery, injections, or medication. Common conditions include failed back surgery syndrome, CRPS, peripheral neuropathy, and limb pain from poor circulation.
What to expect: Like the pain pump, SCS begins with a trial period of five to ten days. If pain reduces by 50% or more, a permanent device is implanted. The stimulator is controlled by a small handheld remote. Most patients report significantly improved ability to walk, sleep, and return to daily activities.
Is Chronic Pain Treatment Covered in Kenya?
SHA (Social Health Authority): The new SHA framework — replacing NHIF — is expanding coverage of specialist procedures. Pain clinic consultations and some injections may be partially covered at accredited facilities. Confirm your benefits directly with SHA before scheduling.
Medical insurance: Most comprehensive private health insurance plans in Kenya cover nerve blocks and epidural steroid injections when prescribed by a specialist. Implantable devices such as pain pumps and spinal cord stimulators are covered selectively — check your policy’s benefit schedule for “implantable pain devices” or “neuromodulation.”
Out-of-pocket patients: For those self-paying, some facilities offer payment plans for high-cost procedures. Always ask.
Finding a Pain Specialist in Kenya
Ask your GP for a referral to a pain management specialist or anaesthesiologist with a pain subspecialty. In Nairobi, dedicated pain clinics operate within Nairobi Hospital, Aga Khan University Hospital, and Karen Hospital. Outside Nairobi, MTRH in Eldoret and Coast General Hospital in Mombasa offer pain management services.
