CRPS is estimated to affect approximately 200,000 Americans, though it is frequently misdiagnosed and underdiagnosed
CRPS Treatment in La Crosse, WI: Ketamine Therapy for Complex Regional Pain Syndrome
Complex regional pain syndrome is one of the most painful and least understood chronic pain conditions that exists. IV ketamine therapy is among the most well-supported treatments for CRPS available, with clinical evidence showing meaningful and lasting pain reduction in patients who have found little relief elsewhere.
CRPS Is One of the Most Painful Conditions Known to Medicine. Ketamine Is One of the Few Treatments That Works.
The McGill Pain Index, a widely used measure of pain intensity, ranks complex regional pain syndrome above childbirth, above bone fractures, and above most other known pain conditions. For people living with CRPS, that ranking matches their daily reality: burning, aching, relentless pain that spreads, intensifies, and doesn’t respond to most standard pain treatments.
IV ketamine therapy is one of the most evidence-backed interventions for CRPS currently available. Research published in the journal Pain demonstrated that ketamine produces effective and long-term pain relief in patients with CRPS Type 1. The mechanism is well understood: ketamine blocks NMDA receptors in the central nervous system, interrupting the central sensitization process that keeps CRPS pain amplified and self-sustaining.
At Relevate Ketafusion, CRPS is one of our priority chronic pain conditions. We offer IV ketamine infusions specifically for CRPS patients, delivered under continuous medical supervision right here in La Crosse, the only IV ketamine clinic in the Coulee Region.


Understanding CRPS: When the Pain Alarm Gets Stuck in the On Position
Complex regional pain syndrome develops when the nervous system’s pain signaling goes into a state of chronic dysregulation, typically following an injury, surgery, or trauma that the pain system fails to recover from normally. The result is a self-perpetuating cycle of extreme pain that spreads beyond the original site, often accompanied by changes in skin color, temperature, and texture, swelling, and hypersensitivity to touch so severe that even light contact becomes unbearable.
There are two types: CRPS Type 1, formerly called reflex sympathetic dystrophy (RSD), occurs without confirmed nerve damage. CRPS Type 2, formerly called causalgia, occurs with confirmed nerve injury. Both involve central sensitization, a process in which the spinal cord and brain become hypersensitized to pain signals, amplifying them far beyond what the original injury warrants. This central sensitization is driven in part by NMDA receptor activity, which is exactly where ketamine intervenes.

CRPS Presentations and Related Conditions We Treat
CRPS varies significantly in presentation, severity, and how far it has spread. Ketamine therapy has shown meaningful benefit across the spectrum, particularly for patients who haven't responded to conventional pain management.
CRPS Type 1 (Reflex Sympathetic Dystrophy)
CRPS Type 1 occurs without confirmed nerve injury and is the more common presentation. A landmark study published in Pain demonstrated that IV ketamine produced effective and long-term pain relief in CRPS Type 1 patients, with meaningful reductions in pain intensity that persisted beyond the treatment period. For patients who have cycled through physical therapy, nerve blocks, medications, and other interventions without adequate relief, ketamine infusion therapy offers a mechanism that addresses the central sensitization driving the pain at its source.
CRPS Type 2 (Causalgia)
CRPS Type 2 involves confirmed nerve injury and typically presents with more severe and persistent symptoms. The central sensitization component that drives Type 2 pain is equally amenable to ketamine's NMDA receptor blocking mechanism. Our medical team will conduct a thorough evaluation to determine the appropriate ketamine protocol for your specific presentation and pain history.
Spreading CRPS
In some cases, CRPS spreads from the original site to other limbs or areas of the body. This spreading reflects the central rather than peripheral nature of the pain process, and it's a clinical indicator that central sensitization is well established. Ketamine therapy's ability to modulate central pain processing makes it relevant for spreading CRPS, and our team will discuss realistic treatment goals and expectations during your consultation.
CRPS with Co-Occurring Depression or Anxiety
Depression and anxiety are extremely common in CRPS, and they make pain significantly worse. Emotional distress amplifies pain perception through shared neurological pathways, and the demoralization of living with intractable pain creates a cycle that's difficult to break. Ketamine therapy's ability to address both chronic pain and the mood disorders that accompany it makes it uniquely well-suited for this combination, addressing both dimensions simultaneously rather than requiring separate treatment tracks.
CRPS with Opioid Dependence
Long-term opioid use for CRPS pain is common and frequently leads to opioid-induced hyperalgesia, a paradoxical condition where opioids actually increase pain sensitivity over time. Ketamine therapy's different mechanism of action makes it a valuable tool for patients seeking to reduce or eliminate opioid use. A published case report documented a CRPS patient going from a pain score of 9 out of 10 to pain-free at 30 days following ketamine infusion, with successful opioid tapering and sustained abstinence at one-year follow-up.
Your CRPS Treatment Journey at Relevate Ketafusion
From your first conversation to your last session, we're with you at every step.
01
Initial Consultation
Your journey starts with a virtual consultation. We'll talk through your CRPS history, your pain patterns, the treatments you've tried, and your goals. Dr. Schumaker will review your case carefully to determine whether IV ketamine is appropriate and what protocol makes the most clinical sense for your presentation. We'll set realistic expectations about what treatment can and can't achieve.
02
Personalized Treatment Plan
CRPS protocols are more individualized than standard mental health infusion protocols. We'll map out your recommended number of sessions, infusion duration, dosing approach, and timeline based on your specific presentation and history. We'll also discuss how ketamine therapy fits alongside any other pain management you're receiving and coordinate with your other providers where appropriate.
03
Treatment Sessions
Every session takes place in a private, calm treatment room with continuous medical supervision. Our team monitors your vitals, your pain response, and your comfort in real time throughout every infusion, adjusting as needed. Plan to have someone drive you home afterward, and allow adequate rest time following each session.
04
Monitoring and Maintenance
We track your pain response carefully across your initial series and adjust the plan based on your results. For CRPS, the duration of pain relief following ketamine treatment varies by patient, and maintenance infusion schedules are built around that individual response. Our goal is the longest possible period of meaningful pain reduction with the least frequent treatment necessary to sustain it.
Our CRPS Treatment: IV Ketamine Infusion
For CRPS, IV ketamine infusion is the primary treatment modality we offer. The IV route provides precise dosing, immediate bioavailability, and the ability to titrate the infusion in real time based on your response, making it the most clinically appropriate delivery method for this condition.
IV Ketamine Therapy for CRPS
CRPS infusion protocols differ from standard mental health infusion protocols. Sessions typically run longer, and the dosing is calibrated specifically for central pain modulation. Your protocol will be determined by Dr. Schumaker based on your specific presentation, pain history, and response. Most CRPS patients complete an initial series of infusions over 2 to 4 weeks, with maintenance infusions scheduled based on how long the pain relief is sustained. IV ketamine is a self-pay treatment and not covered by insurance.

Spravato (Esketamine) Therapy
Spravato is FDA-approved for treatment-resistant depression and MDD with suicidal ideation. For CRPS patients who also experience significant depression or anxiety, Spravato may be considered as a complementary option for the mood components of their condition. Your provider will discuss whether this makes sense for your specific situation during your consultation. Spravato is covered by most major insurance plans.

The Science Behind Ketamine for CRPS
CRPS involves a process called central sensitization, in which the spinal cord and brain become abnormally sensitized to pain signals. NMDA receptors play a central role in establishing and maintaining this sensitization. When NMDA receptors are overactivated by persistent pain signals, they lower the threshold at which pain is perceived, amplify incoming signals, and create a self-sustaining cycle of pain that persists even after the original injury has healed.
Ketamine is a potent NMDA receptor antagonist. By blocking these receptors, it interrupts the central sensitization process, essentially resetting the pain system’s abnormal gain settings. This is not symptom management. It’s an intervention at the neurological mechanism driving CRPS pain. The effect can be lasting, with pain relief persisting well beyond the duration of ketamine’s direct pharmacological action, suggesting that blocking NMDA receptors allows the central sensitization process to begin unwinding.

Why Choose Relevate Ketafusion for CRPS Treatment
01
Among the Most Evidence-Backed Applications of Ketamine
Of all the conditions ketamine therapy addresses, CRPS has one of the strongest and most established evidence bases. This isn’t emerging research. It’s well-established clinical science with peer-reviewed publications and decades of use in pain management settings. We approach CRPS treatment with that confidence, while being honest about individual variation in response.
02
A Medical Director Who Understands Pain at the Molecular Level
Dr. Howard Schumaker’s dual board certifications in Family and Emergency Medicine, combined with his chemical engineering background, mean he understands ketamine’s mechanism of action in central pain modulation at a depth most clinicians don’t. He personally oversees every CRPS treatment protocol at Relevate, bringing both clinical expertise and molecular-level understanding to your care.
03
The Only IV Ketamine Clinic in the Coulee Region
Relevate Ketafusion is the only provider in the La Crosse area offering IV ketamine infusions. The nearest alternative is over two hours away. For someone living with CRPS-level pain, that drive isn’t just inconvenient. It’s a genuine barrier to accessing treatment that could dramatically change your quality of life.
04
Continuous Medical Supervision at Every Session
Every session happens under direct medical supervision with continuous vital sign monitoring. Our team adjusts your infusion in real time based on your response, ensuring both safety and optimal therapeutic effect. For a condition as serious as CRPS, that level of attentiveness is essential.
05
Addressing Pain and Mood Together
Depression and anxiety in CRPS patients aren’t separate problems requiring separate treatment. They share neurological pathways with pain and actively amplify it. Ketamine therapy addresses both simultaneously, which is a clinical advantage no other available CRPS treatment can claim.
06
A Transparent, Honest Approach to Treatment
We won’t promise a cure for CRPS. What we will promise is an honest evaluation of your case, a treatment protocol built around your specific presentation, and a team that tracks your response carefully and adjusts accordingly. Some patients achieve dramatic long-term relief. Others achieve meaningful reduction. Our job is to give you the best possible outcome with full transparency about what that looks like for you.
