Radiofrequency ablation (RFA) is a minimally invasive, image-guided procedure that uses controlled heat to interrupt the nerves carrying chronic pain signals from a damaged joint or spinal level. For patients across the Clear Lake and Bay Area Houston communities living with persistent low back, neck, or knee pain that has not responded to conservative care, RFA offers six to twelve months of meaningful relief without surgery, general anesthesia, or the long drive into the Texas Medical Center.
At the League City office of Performance Pain and Sports Medicine, located on East Main Street just minutes from I-45 and the South Shore Harbour waterfront, Dr. Suzanne Manzi performs radiofrequency ablation under fluoroscopic guidance to treat lumbar and cervical facet joint pain, sacroiliac joint dysfunction, and chronic knee pain from osteoarthritis. Every case begins with a focused evaluation and a diagnostic medial branch block to confirm the precise nerve source before any heat lesion is performed.
If physical therapy, medication, and steroid injections have reached the limits of what they can do for you, RFA is one of the most thoroughly studied interventional pain procedures available and a natural next step for many Clear Lake area patients.
What Is Radiofrequency Ablation?
Radiofrequency ablation is a non-surgical procedure that uses radiofrequency energy to generate a precise, controlled heat lesion on targeted nerve tissue. This heat disrupts the nerve’s ability to send pain signals to the brain, providing relief that can last for several months or longer.
The procedure is performed under fluoroscopic guidance, a form of real-time X-ray imaging that allows the treating physician to place the treatment needle with pinpoint accuracy. The American Society of Interventional Pain Physicians (ASIPP) considers fluoroscopic or CT guidance mandatory for all facet joint interventions, including RFA (Manchikanti et al., Pain Physician, 2020).
RFA does not permanently destroy nerves. The targeted nerve fibers can regenerate over time, which is why pain may gradually return after 6 to 12 months or longer. When that happens, the procedure can be repeated. A systematic review of randomized controlled trials found that RFA provides statistically significant pain reduction for patients with lumbar facet joint and sacroiliac joint pain (Leggett et al., Pain Research & Management, 2014).
RFA is not appropriate for every type of pain. It works best when the pain source has been confirmed through a diagnostic nerve block prior to the procedure.
Conditions Treated with RFA in League City
League City sits in the heart of Bay Area Houston, halfway between the Texas Medical Center and the Gulf coast, and the patients we see at the East Main Street office reflect that geography. Many work at NASA Johnson Space Center or for aerospace contractors like Boeing, Lockheed Martin, Jacobs, and Barrios. Others commute to the Houston Ship Channel, Bayport, or Texas City refineries and chemical plants. We also treat a steady flow of UTMB Health and Houston Methodist Clear Lake clinicians, Clear Creek ISD educators, active retirees boating on Clear Lake and Galveston Bay, and youth athletes’ parents shuttling between Big League Dreams and high school stadiums.
Conditions commonly treated with RFA at the League City office include:
- Lumbar facet joint pain, a leading cause of chronic low back pain among NASA engineers and aerospace contractors who spend long days in console seats, refinery and chemical-plant operators with years of repetitive lifting, and active-adult boaters whose lower back has logged thousands of hours of marina lifestyle.
- Cervical facet joint pain and cervicogenic headaches, a frequent finding in surgical and procedural clinicians at UTMB and Methodist Clear Lake, dental providers, and astronaut training staff who hold sustained forward head posture. A systematic review found Level II evidence supporting cervical facet RFA for chronic neck pain (Suer et al., Pain Physician, 2022).
- Sacroiliac joint pain, a common driver of one-sided low back and buttock pain in patients with prior lumbar surgery, post-pregnancy structural changes, or jobs that involve repeated climbing in and out of trucks, boats, and offshore vessels around Galveston Bay.
- Genicular nerve pain from knee osteoarthritis, a non-surgical option for active retirees on the Clear Lake water, longtime CCISD educators, and pre-replacement patients across the Bay Area who want to delay or avoid total knee replacement and stay on the boat, in the gym, and at the ballpark.
Each condition requires a confirmed diagnosis through a diagnostic medial branch or lateral branch block before RFA is recommended.
How Radiofrequency Ablation Works
The path from your first League City consultation to a definitive radiofrequency procedure follows a deliberate, evidence-based sequence designed to confirm exactly which nerves are generating your pain before any treatment is performed. This protects Bay Area patients from undergoing a procedure that does not match the true source of their pain and gives you the best chance of meaningful, durable relief.
Step 1: Consultation and Evaluation
Your first visit at the League City office begins with a comprehensive interventional pain evaluation. Dr. Manzi reviews your medical history, prior imaging, physical therapy notes, prior injections, and current medications. A focused physical exam, range-of-motion testing, and pattern-of-pain analysis help determine whether your symptoms are consistent with facet joint, sacroiliac, or knee-mediated pain that may respond to RFA. If new imaging is needed, it is coordinated locally rather than requiring a trip up I-45 into the Texas Medical Center.
Step 2: Diagnostic Medial Branch Block
Before any radiofrequency lesion is performed, Dr. Manzi uses a diagnostic medial branch block to confirm that the nerves you intend to treat are in fact the source of your pain. A small amount of local anesthetic is injected near the medial branch nerves under live fluoroscopic guidance in the League City office. If the block produces meaningful temporary pain relief, that result confirms those nerves are transmitting your pain signals and predicts a strong response to RFA. If the block does not relieve your pain, your team reassesses the diagnosis rather than proceeding with a treatment that is unlikely to help.
Step 3: RFA Procedure Day in League City
On procedure day, you arrive at the East Main Street office, where Dr. Manzi performs the radiofrequency procedure under fluoroscopic guidance. After the skin and deeper tissues are numbed with a local anesthetic, a thin specialized needle is advanced precisely to the targeted medial branch, lateral branch, or genicular nerve. A microelectrode at the tip delivers radiofrequency energy that heats the nerve tissue to a controlled, measured temperature, disrupting its ability to transmit pain signals while leaving surrounding muscle and bone unaffected.
The procedure typically takes 30 to 60 minutes. Most patients walk out the same day and have a friend or family member drive them home. Because Bay Area summers are hot and humid and hurricane season runs June through November, our team will give you written aftercare guidance tailored to local conditions: hydration, indoor recovery in air conditioning, and a backup plan if a tropical system disrupts a follow-up visit. For broader context on related conditions, see our back pain treatment overview.
Benefits of Radiofrequency Ablation
Radiofrequency ablation is one of the most thoroughly studied non-surgical options for chronic facet and sacroiliac joint pain. A systematic review and meta-analysis found that all three commonly used RFA techniques delivered significant pain improvement for up to 12 months with no serious complications reported (Shih et al., Clinical Neurology and Neurosurgery, 2020).
Patients across Clear Lake and the Bay Area commonly cite the following advantages when they choose RFA at the League City office:
- Six to twelve months of meaningful relief. Many patients describe a return to walking the marina at South Shore Harbour, completing a full shift on a turnaround crew, or sleeping through the night again after months or years of disrupted rest.
- Truly minimally invasive. RFA uses a thin needle and local anesthetic. There are no incisions, no stitches, and no general anesthesia, so there is no hospital admission and no operating-room time.
- Same-day, in-office procedure. Most League City patients are home within an hour and back to light activity within two to three days, which fits the schedules of NASA contractors, refinery shift workers, and parents of CCISD athletes.
- Less reliance on chronic pain medication. By directly interrupting the pain signal, RFA can reduce the need for daily oral analgesics, an important goal for patients in safety-sensitive aerospace, refinery, and offshore roles.
- Repeatable when relief fades. Because the targeted nerves naturally regenerate, RFA can be safely repeated in the same office to maintain control of your pain.
- Surgery-sparing. For patients exploring alternatives to spinal fusion or knee replacement, RFA is a proven interventional option that fits between conservative care and surgery and lets you stay on the boat, in the gym, and on the job.
Your individual results will depend on your specific diagnosis, the nerves treated, and how your body responds to the procedure.
Risks and What to Expect After RFA
Radiofrequency ablation is considered a low-risk procedure, but every League City patient receives a frank discussion of possible side effects before consenting to treatment.
Common, self-limiting effects (typically resolve within one to two weeks):
- Mild soreness or a deep ache at the treatment site
- Temporary numbness or altered sensation in the treated area
- Minor bruising or local swelling
Rare effects:
- Infection at the needle insertion site
- Prolonged numbness or new nerve irritation
- Allergic reaction to the local anesthetic
Serious complications from RFA are uncommon. The Shih et al. (2020) meta-analysis cited above reported no serious complications across the studies reviewed.
Recovery and seasonal considerations:
Most League City patients return to light daily activity within a few days. Mild soreness at the procedure site is normal for one to two weeks. The full pain-relieving effect typically develops over two to four weeks as the treated nerve responds to the heat lesion. Because Bay Area summers are hot and humid and hurricane season runs from June through November, your team will discuss hydration, indoor air-conditioned recovery, and a contingency plan for follow-up if a tropical storm or hurricane disrupts scheduling. A follow-up visit is scheduled at the League City office to evaluate your response and adjust your care plan if needed.

Do you accept referrals from Bay Area primary care, neurosurgeons, and orthopedists?
Yes. Dr. Manzi routinely accepts referrals from UTMB Health, Houston Methodist Clear Lake, HCA Houston Healthcare Clear Lake, NASA contractor health programs, and independent primary care, neurology, neurosurgery, orthopedic, and physical therapy practices throughout the Clear Lake / Bay Area. Most patients are seen within one to two weeks. Records can be sent through your referring practice or directly to the League City office at 346-217-1111.
How long does radiofrequency ablation last?
Most League City patients experience six to twelve months of meaningful pain relief. Some report relief well beyond a year. Because the treated nerves can regenerate over time, pain may gradually return. When it does, RFA can be repeated in the same office. Clinical evidence supports significant pain reduction lasting up to 12 months across multiple RFA techniques (Shih et al., 2020).
Is radiofrequency ablation painful?
Most patients tolerate the procedure well. Dr. Manzi applies a generous local anesthetic to numb the skin and deeper tissues before any RFA needle is placed. You may feel a brief sensation of pressure or warmth during the radiofrequency portion. Mild oral sedation is available for patients who prefer it for comfort or anxiety.
How long is recovery after RFA at the League City office?
Most patients return to light daily activities within two to three days. Mild soreness at the treatment site is common for one to two weeks. The full pain-relieving effect typically develops over two to four weeks. Because Bay Area summers are hot and humid and hurricane season runs June through November, your team will discuss hydration, indoor air-conditioned recovery, and a contingency plan if a tropical system disrupts a follow-up visit.
Does insurance cover radiofrequency ablation?
Most insurance plans cover RFA when it is medically necessary and a diagnostic medial branch block has confirmed the pain source. Coverage details vary by plan. Call the League City office at 346-217-1111 to confirm your benefits before scheduling.
What is the difference between a nerve block and RFA?
A medial branch block is a diagnostic injection that temporarily numbs a target nerve to confirm it is the source of your pain. Radiofrequency ablation is the therapeutic procedure that follows, using a controlled heat lesion to interrupt that same nerve for longer-lasting relief. The block typically lasts hours; the RFA can provide six to twelve months or more of relief.
Schedule Your League City RFA Consultation
If chronic back pain, neck pain, or knee pain has not responded to physical therapy, medication, or steroid injections, radiofrequency ablation may help you find lasting relief without surgery. Patients across the Clear Lake and Bay Area Houston community are welcome to schedule a consultation at the League City office to discuss whether RFA is right for your condition.
