Condition

CRPS

CRPS is a chronic pain condition where a limb becomes intensely painful, often after an injury or surgery. The pain feels out of proportion to what caused it, and everyday touch or cold can be unbearable. It is treatable.

Overview

Complex Regional Pain Syndrome happens when the nervous system stays on high alert after an injury. The affected limb becomes hypersensitive, with burning pain, color changes, swelling, and sometimes temperature differences.

Early, targeted treatment makes a real difference. Sympathetic nerve blocks, in particular, can reset the pain signal before CRPS becomes entrenched.

Symptoms & causes

CRPS has a recognizable pattern. Catching it early is the single biggest factor in long-term outcome.

Severe burning, aching, or throbbing pain in an arm or leg
Hypersensitivity to touch, temperature, or clothing over the affected limb
Color, temperature, or sweating differences compared to the other side
Swelling, stiffness, or reduced use of the affected limb

When to see a doctor

Seek care if…

Call us quickly if symptoms are spreading to other limbs, if there are new signs of swelling, infection, or vascular compromise, or if the pain becomes severe enough to interfere with sleep and daily function.

Frequently asked questions

What causes CRPS?

It usually starts after an injury, surgery, or immobilization. The nervous system essentially gets stuck in a high-alert mode. Exactly why some people develop it and others do not is still being studied, but early treatment changes the course.

Will CRPS go away on its own?

Some mild cases do. Many do not, and waiting can let the condition become more entrenched. Early, targeted treatment offers the best chance at full recovery.

How soon should I see a specialist?

As soon as the pattern is suspected. If a limb is disproportionately painful weeks after an injury or procedure, please get in quickly. Time matters with CRPS.
