Complex Regional Pain Syndrome is among the most treatment-resistant and high-severity pain conditions documented in clinical medicine — frequently described by patients as a burning, unrelenting pain that resists opioids, nerve blocks, and physical therapy alike. At KDI Health in Frisco, TX, we offer IV and IM ketamine for patients with CRPS, fibromyalgia, chronic neuropathic pain, and other refractory pain syndromes. This is not an emerging curiosity; ketamine’s role in pain management predates its emergence in psychiatric medicine and is grounded in one of the most studied receptor mechanisms in pain pharmacology.
How Ketamine Works for Chronic Pain: The NMDA Mechanism
Ketamine’s analgesic mechanism centers on its antagonism of NMDA receptors in the spinal cord and brain. In chronic pain conditions, the nervous system undergoes a process called central sensitization — the spinal cord and higher cortical centers become progressively more reactive to pain signals, amplifying them beyond the level that the original injury or disease would warrant. This sensitization is thought to drive the persistence and intensity of pain in conditions like CRPS and fibromyalgia even after the initiating injury has resolved or the peripheral inflammation has diminished. Ketamine’s NMDA blockade interrupts this central sensitization, potentially restoring more normal pain processing for a period following treatment.
Physician-Led Chronic Pain Care at KDI Health in Frisco, TX
At KDI Health, our approach to chronic pain reflects the same principles that guide our psychiatric practice. Dr. Stephen Gasper personally evaluates every patient presenting with a pain indication — reviewing the specifics of the diagnosis, prior treatment history, comorbid conditions, and contraindications — before designing a protocol. Dr. Gasper’s background in emergency medicine, where the assessment and management of acute and complex pain is a core competency, informs how he approaches chronic pain presentations. He is not applying a psychiatric template to a pain problem; he is drawing on training in pain physiology and acute care that most ketamine clinicians do not share.
One distinction we make explicitly is the difference between outpatient ketamine protocols and the intensive high-dose multi-day protocols sometimes used for severe CRPS in hospital settings. Our protocols are calibrated to what can be safely and effectively administered on an outpatient basis in Frisco. For patients with the most severe CRPS presentations, we will tell you directly whether your situation requires a level of care beyond what an outpatient clinic can provide. We believe that honesty — even when it means referring a patient elsewhere — is more valuable than overpromising.
Setting Honest Expectations for Chronic Pain Patients
The barrier we encounter most consistently with chronic pain patients is the long journey they have been on before they reach us. Many have spent years navigating the pain management system — multiple specialists, medications, injections, surgeries, spinal cord stimulators — and carry a justified exhaustion and skepticism about any new option. We take that history seriously and do not ask patients to trust us on the basis of enthusiasm. We walk through the specific evidence for ketamine in their particular condition, discuss what realistic outcomes look like, and let patients make informed decisions. Results vary by individual, and that is not a legal disclaimer — it is a genuine clinical reality that we communicate clearly.
Addressing Concerns About Ketamine and Dependence
The second barrier is concern about ketamine’s association with recreational use and addiction. Ketamine does carry a risk of dependence with unregulated chronic use — this is real and documented. At KDI Health, our protocols are structured, physician-supervised, and designed to minimize any dependence risk. Dr. Gasper is present at every session, dosing is medically controlled, and the treatment is not self-administered. The clinical use of ketamine under physician supervision is categorically different from unsupervised recreational use, and we explain that distinction honestly to every patient who raises it.
Treating Chronic Pain Alongside Co-Occurring Depression and PTSD
For chronic pain patients whose pain co-occurs with depression — which is extremely common and bidirectional — ketamine’s dual mechanism may address both the pain and mood components of their condition simultaneously. This is one of the more clinically compelling aspects of ketamine in this population. Treating the pain in isolation, while the depression remains unaddressed, often produces partial results. We assess for depression, anxiety, and PTSD in every chronic pain patient we evaluate and design protocols that reflect the full picture.
Both IV and IM ketamine are available at KDI Health for pain indications. The choice between delivery methods depends on your clinical picture, venous access, and response profile. We discuss this during your consultation with Dr. Gasper.
FAQ
Is ketamine FDA-approved for CRPS or fibromyalgia?
No. Ketamine’s use for chronic pain conditions is off-label. Its FDA approval is limited to anesthesia. Clinical evidence supports its use in central sensitization disorders, but it is not FDA-approved for CRPS, fibromyalgia, or other chronic pain indications. Please discuss your situation with your provider.
How does ketamine reduce chronic pain?
Ketamine antagonizes NMDA receptors in the spinal cord and brain, interrupting the central sensitization that amplifies pain in conditions like CRPS and fibromyalgia. This mechanism addresses the nervous system’s altered pain processing rather than just blocking pain signals peripherally.
Does KDI Health offer IV and IM ketamine for pain?
Yes. Both IV and IM ketamine are available for chronic pain indications. The appropriate delivery method depends on your diagnosis, severity, and response profile. Dr. Gasper makes this determination during your consultation.
How many sessions are needed for chronic pain?
Pain protocols vary more than psychiatric protocols. Some patients complete four to six infusions over one to two weeks; others require repeat series. We design the protocol based on your specific diagnosis and response and adjust as needed.
Can ketamine help pain that has not responded to opioids?
Possibly. Ketamine’s mechanism is distinct from opioid receptor pathways, meaning it can work independently of — or alongside — opioid management. Whether it is appropriate for your specific pain situation depends on your clinical history. Dr. Gasper evaluates this during consultation.
Key Takeaways
- Ketamine addresses chronic pain by blocking NMDA receptors and interrupting central sensitization, a mechanism distinct from opioids and most other analgesics.
- Both IV and IM ketamine are available at KDI Health for CRPS, fibromyalgia, and other refractory pain conditions.
- Dr. Gasper’s emergency medicine background informs his approach to pain evaluation and protocol design.
- Chronic pain frequently co-occurs with depression and PTSD; KDI Health evaluates and addresses the full clinical picture.
- Results vary by individual; outpatient protocols are appropriate for most chronic pain patients but the most severe CRPS cases may require higher-intensity settings.
Chronic pain is not simply physical — it reaches into every part of a person’s life. At KDI Health, we see that clearly and we take it seriously. If you are living with CRPS, fibromyalgia, or another refractory pain condition in Frisco or the broader DFW area and have not found adequate relief through conventional care, we encourage you to reach out for a consultation. Discuss your full history with your provider, and let us explore whether ketamine therapy may be part of the answer.
About Dr. Stephen Gasper
Dr. Stephen Gasper is the owner and medical director of KDI Health Ketamine Clinic, which he founded in early 2021 in Frisco, TX. At the age of 17, he enlisted in the Marines, serving four years as a forward observer in the infantry. He then moved to Texas and obtained his BS in Biology from the University of Dallas. Dr. Gasper received his Medical Degree from UTHealth Houston in 2011 and practiced medicine in the DFW area for over 10 years as a board-certified Emergency Physician. He was inspired to found KDI Health during the COVID pandemic because of the effectiveness of ketamine as a therapy for veterans and the broader community struggling with depression, anxiety, and PTSD. Dr. Gasper personally oversees every session administered at the clinic and sees one patient at a time, providing direct physician oversight throughout each treatment.
