CRPS Flares and Treatment Options for Complex Regional Pain Syndrome in Littleton, CO
Complex regional pain syndrome, often called CRPS or RSD, can make an ordinary sensation feel impossible to tolerate. If you are looking for CRPS treatment, complex regional pain syndrome treatment, or RSD treatment, you may already know how disruptive and isolating this condition can be.
A sleeve brushing your arm, a bedsheet resting on your foot, a change in room temperature, or the pressure of a shoe may trigger burning, stabbing, electric, or deeply aching pain. We know that CRPS symptoms are often visible only to the person living with them. Yet the pain can interrupt sleep, work, movement, and relationships.
If you are searching for answers after an injury, surgery, fracture, or unexplained limb pain, it helps to know that CRPS is real. It is a complex pain condition that can involve the nervous system and changes in the affected limb.
When pain becomes out of proportion
CRPS often begins after an injury or medical event. The original event may have seemed relatively minor. Pain can persist beyond expected healing and may feel out of proportion to the initial injury.
Symptoms often affect an arm, hand, leg, or foot. Still, CRPS does not look or feel the same for everyone. A diagnosis is clinical. No single blood test or scan can confirm CRPS by itself. Instead, a qualified clinician considers your history, symptoms, physical findings, and other possible causes. Diagnostic guidance for CRPS emphasizes assessing sensory, temperature or color, swelling or sweating, and movement or skin changes together (van der Spek et al., 2025).
Common signs can include:
Burning, throbbing, squeezing, or electric pain
Allodynia, pain from something that would not normally hurt, such as light touch or clothing
Heightened pain from a typically painful stimulus, also called hyperalgesia
Swelling, sweating changes, or skin that feels unusually warm or cold
Color changes, including redness, paleness, or a bluish appearance
Stiffness, weakness, tremor, reduced range of motion, or difficulty using the limb
Changes in hair growth, nails, or skin texture over time
Symptoms can fluctuate. One day, the limb may look nearly typical. Another day, swelling, sensitivity, or color changes may be clear. That inconsistency does not make the pain less real.
Why a CRPS flare can feel so overwhelming
A flare is more than a bad pain day. It may bring a sharp rise in burning pain, touch sensitivity, swelling, temperature changes, sleep disruption, and fear of the next trigger. Movement can become difficult. At the same time, avoiding all movement may make everyday function harder over time.
Flares may follow physical strain, illness, stress, poor sleep, or temperature exposure. Sometimes there is no obvious trigger. The nervous system can become highly protective and continue sending danger signals after tissue healing. Research on CRPS mechanisms describes interactions among sensory processing, inflammation, and immune signaling (Okumo et al., 2021).
During a flare, we encourage you to return to the plan you have developed with your medical team. That may mean pacing activity, protecting sleep, taking prescribed medications as directed, and contacting your clinician if symptoms are escalating or changing in a new way.
Sudden weakness, fever, rapidly increasing swelling, signs of infection, chest pain, or shortness of breath need prompt medical attention.
Early attention and steady rehabilitation matter
CRPS can be difficult to identify, especially early on. Its symptoms may resemble the expected aftermath of an injury. Still, the value of early detection is well recognized because timely evaluation can support earlier symptom management and coordinated care (Harnik et al., 2023).
Treatment planning often involves more than one discipline. Your broader care team may include a primary care clinician, pain specialist, physical or occupational therapist, behavioral health professional, and other specialists. The goal is not to force your body through pain. It is to create a plan that respects your limits while supporting mobility, function, and daily life.
Rehabilitation can be an important part of that process. A review of rehabilitation approaches found they may help address pain and disability in CRPS, while also underscoring the need for individualized care (Shafiee et al., 2023). Gentle, consistent work is often more sustainable than an all-or-nothing push on a rare good day.
CRPS treatment, complex regional pain syndrome treatment, and RSD treatment
There is no universal plan for CRPS treatment. A useful plan begins with a careful assessment. We look at where pain occurs, how symptoms have changed, what you have already tried, your medical history, and what you most want to be able to do again.
Your care may include medication management through your prescribing clinician, physical or occupational therapy, desensitization work, movement strategies, sleep support, mental health care, and interventional pain options. Current CRPS management literature supports a multidisciplinary approach because CRPS can affect pain, function, mood, and quality of life at once (Abd-Elsayed et al., 2024).
We also encourage you to track patterns without becoming consumed by them. A simple record of sleep, activity, temperature exposure, flare intensity, and medication changes can give your care team useful context. It may also help you notice small changes that pain can otherwise obscure.

IV ketamine therapy for CRPS
At Vitalitas Denver, we offer IV ketamine therapy for CRPS after an individual medical assessment. Ketamine for chronic pain, including CRPS, is an off-label use. This means the FDA has not specifically approved ketamine for CRPS, though clinicians may use it in carefully selected situations with medical supervision.
Ketamine interacts with NMDA receptors and glutamate-related pathways involved in pain signaling. You can learn more about glutamate signaling and why it is part of the conversation around complex pain. We take time to review your health history, medications, prior treatments, symptoms, and safety considerations before discussing whether IV ketamine therapy may be appropriate.
Suitability is personal. Some medical or psychiatric factors may affect whether treatment is advisable or how it should be structured. We do not see ketamine as a replacement for the rest of your care. It may be one part of a broader plan that also includes movement, medical follow-up, and support for the emotional weight of persistent pain. You can explore CRPS and ketamine care for a closer look at that conversation.
A next step does not have to mean doing everything at once
When CRPS has narrowed your world, the next step can simply be a thorough conversation. We serve patients from Littleton and surrounding communities, including those seeking ketamine care in Denver. We will listen to what has changed, what you have already carried, and what you need from a treatment plan.
You may also find it helpful to read about ketamine for chronic pain as you consider questions to bring to your care team.
If chronic pain has left you feeling hopeless or unsafe, immediate support matters. You can call or text 988 to reach the 988 Suicide and Crisis Lifeline anytime in the United States (988 Suicide and Crisis Lifeline, n.d.). You do not have to wait until things become unbearable to ask for help.
