Complex regional pain syndrome can make ordinary decisions feel exhausting. You may be living with pain that changes from day to day, a limb that feels unfamiliar, sleep that has become fragile, and a medical history that is already full of appointments. By the time ketamine enters the conversation, most people are not looking for another vague possibility. They want clear questions and honest answers.
At Edelica Health, we believe an infusion evaluation should be a conversation, not a sales pitch. Ketamine for CRPS is an individualized medical decision, and it is an off-label use of ketamine. That does not make the conversation less worthwhile. It makes the details more important.
CRPS is not a simple pain condition. It may involve ongoing regional pain along with changes in sensation, temperature, color, swelling, sweating, movement, or function. A comprehensive review of CRPS describes how varied these symptoms can be, and why the condition often requires careful, ongoing assessment (Taylor et al., 2021). Before you consider infusion treatment, these are the questions we encourage you to bring with you.
Start with the diagnosis and the whole picture
The first question is straightforward: Do we feel confident that CRPS is the right diagnosis?
CRPS is diagnosed clinically. There is no single blood test or scan that can establish it on its own, and clinicians also need to consider other causes of pain, swelling, nerve symptoms, and limited movement. Current evidence-based guidance emphasizes the importance of a careful history and physical examination in this process (Limerick et al., 2023).
We will want to understand when your symptoms began, whether there was an injury or surgery beforehand, how the pain has changed, and what it now prevents you from doing. Bring records if you have them. Imaging, procedure notes, medication lists, prior pain-clinic documentation, and notes from physical or occupational therapy can all help us see the fuller arc of your care.
You might ask:
What information do you need before deciding whether I am a candidate?
Are there other conditions that could be contributing to my symptoms?
What are the goals we are trying to define, pain reduction, better sleep, greater ability to participate in therapy, or something else?
How will we know whether treatment is helping in a meaningful way?
We also encourage you to talk with us about your current care. Our work with chronic pain treatment begins with the recognition that pain affects more than one system, and that your existing clinicians may hold important parts of the story.
Ask what ketamine can and cannot answer
Ketamine has been used in anesthesia for decades. In pain care, IV ketamine is sometimes considered for CRPS, but it is not a universal answer and it should not be presented as one. The research literature is encouraging in some areas, yet limited by differences in study designs, dosing approaches, patient populations, and how long outcomes were followed.
A systematic review of ketamine in CRPS found evidence suggesting potential benefit while also underscoring the need for stronger, more consistent studies (Connolly et al., 2015). A later review similarly noted that ketamine protocols and responses vary considerably across the literature, including variation in dosing practices and duration of response (ketamine dosing and response research (Lii et al., 2023)).
That is why we do not begin with promises. We begin with your history and your goals.
Ask us directly:
Why are you considering ketamine in my particular situation?
What would make you advise against infusion treatment right now?
What kind of response is realistic to discuss, given my history?
What does the evidence tell us, and where are its limits?
If I do not experience the change we hoped for, what happens next?
Our page on ketamine for CRPS offers more context on this conversation, but an evaluation is where your personal medical picture matters most.
Review your medications, health history, and daily risks
A safe evaluation is not limited to the diagnosis. We review your full medication list, including prescriptions, over-the-counter products, supplements, and any substances you use. We also want to know about prior anesthesia experiences, medication reactions, blood pressure concerns, heart conditions, liver disease, sleep problems, and psychiatric history.
Be especially open about alcohol use, cannabis, opioids, benzodiazepines, stimulants, and medications prescribed for mood, sleep, or attention. This is not about judgment. It is about making thoughtful decisions and avoiding surprises.
Questions worth asking include:
Which medications should I continue, adjust, or avoid before an infusion?
Are there medical conditions that change the risk of ketamine treatment?
How will you monitor my blood pressure, comfort, and level of alertness?
What side effects might occur during or after an infusion?
Who should I contact if I have concerns once I am home?
Ketamine can cause temporary changes in perception, dissociation, nausea, dizziness, or elevations in blood pressure. The experience can be unfamiliar. We talk through it beforehand so that you are not left trying to interpret it alone in the moment.
Understand the schedule before you commit
Pain treatment has a practical side. You need to know what an appointment requires of your body, your calendar, and the people who help you get through the week.
Ask about the anticipated length of each visit, the number and spacing of infusions being considered, how progress will be assessed, and whether a support person should drive you home. Do not assume you will be ready to return immediately to work, caregiving, or other demanding responsibilities after an infusion. Planning a quieter day is often wise.
Our first infusion preparation guide can help you think through transportation, meals, clothing, and the questions you may want to write down in advance. You can also ask whether you should arrange time away from physical therapy, or whether your therapy schedule may be an important part of the plan.
A review of current CRPS management notes that care is often multidisciplinary, bringing together medical treatment with rehabilitation and psychological support when appropriate (Abd-Elsayed et al., 2024). In other words, an infusion should fit into your life of care. It should not erase the rest of it.
Make care coordination part of the plan
Many people with CRPS already have a primary-care clinician, pain specialist, therapist, surgeon, neurologist, physical therapist, or occupational therapist. We do not view those relationships as obstacles. They are part of the foundation.
Before treatment, ask:
Can you communicate with my existing clinicians if I authorize it?
How will you share recommendations or treatment updates?
How might this fit alongside physical or occupational therapy?
What should my other providers know about my treatment plan?
Our approach has always been to place infusion therapy in the broader context of your health care. We want to understand not only your pain score, but also your function, your support system, and the pressures you are carrying. Our ketamine support system resource speaks to the practical value of having people around you who understand what treatment days may require.
Give yourself permission to decide slowly
You do not have to decide during a first conversation. A good evaluation should leave room for questions, reflection, and discussion with the people you trust. You may decide that ketamine treatment is worth considering. You may decide the timing is not right. Either response can come from careful judgment.
If chronic pain has left you feeling isolated, we want you to know that you do not have to organize this decision by yourself. We invite you to reach out to Edelica Health in Milwaukee at 414-441-5707 to schedule a consultation and talk through whether ketamine for CRPS deserves a place in your care plan.
