If you developed complex regional pain syndrome (CRPS) after an injury, you know it’s more than just minor lingering pain — it’s a chronic pain condition that constantly aggravates the injured nerves and affects the entire limb’s sensation, appearance, and function.
What makes CRPS especially tricky is that it can cause symptoms beyond pain. If you’ve ever felt confused or frustrated when doctors tell you “everything looks normal,” you’re not alone.
At SamWell Institute for Pain Management in Colonia, Livingston, and Engelwood, New Jersey, Dr. Jay M. Shah and our team take a patient-centered approach that starts with listening to your story.
Together, we can help you understand CRPS better, and that means knowing both the common and the unexpected symptoms — because early recognition can lead to earlier relief.
CRPS can cause a variety of symptoms, many of which overlap with other conditions. Typically, people with CRPS experience:
These symptoms are well-known and make sense when you think about the nerve damage that causes them. Other symptoms tend to surprise people because they don’t immediately seem connected to “pain.”
Below are four symptoms that many people with CRPS find unexpected but are important to recognize.
One of the more surprising symptoms of CRPS is that your affected arm or leg may feel cold when the other limb feels warm — or vice versa. This isn’t just “feeling different”; it’s an actual physiological change caused by autonomic nervous system dysfunction.
CRPS disrupts the nerves that regulate blood flow and temperature, leading to temperature differences that can shift from day to day. You might notice your hand suddenly feels icy, then suddenly warm, without any clear cause.
Your skin may change in ways you may not automatically associate with your injury. For example, some people report blotchy, red, or purplish skin on the affected limb. Others notice that the skin looks shiny or thinner than usual.
These changes happen because CRPS affects not only pain nerves but also the small nerves that control blood vessels and skin cells. Over time, this can alter how your skin looks and feels.
It’s not just your skin that can change — the structures on your skin can, too. Unexpectedly fast hair growth, slower hair growth, thickening nails, or brittle nails can all occur in CRPS.
These changes may come and go and often correlate with the intensity of other symptoms. They’re linked to the same autonomic nerve dysfunction that affects skin and temperature. You may be surprised to learn that a pain condition can influence something like nail growth — but it’s a real part of how CRPS can alter normal physiology.
When you think of CRPS, you think of pain — but CRPS doesn’t just hurt. It can also interfere with how your affected limb moves.
Difficulties with coordination, weakness, or a decreased ability to make fine movements can develop over time. You might have swelling or stiffness that makes simple tasks harder, or you find yourself guarding your limb and using it less. Losing your normal ability to move your limb may be surprising, especially if the initial injury seemed minor by comparison.
This motor dysfunction can become self-reinforcing: Avoiding movement due to pain may cause more weakness or stiffness, making your limb feel even less reliable. That’s why specialized pain management and rehabilitation are such critical parts of care.
At SamWell Institute for Pain Management, Dr. Jay M. Shah starts with a comprehensive evaluation that looks beyond pain intensity. He listens to how your symptoms began, where they occur, and how they’ve evolved — whether it’s burning pain, skin changes, sensitivity to touch, movement difficulties, or temperature fluctuations.
Your evaluation may include:
Dr. Shah develops a personalized treatment plan that addresses your unique CRPS symptoms. Your plan could include interventional procedures, physical therapy coordination, and medication management tailored to your specific needs. He also specializes in more targeted relief treatments, such as:
If you’re experiencing persistent pain along with unusual symptoms such as temperature changes, skin discoloration, or changes in hair or nail growth — especially following an injury — it’s worth discussing with a pain specialist.
