CRPS, short for Complex Regional Pain Syndrome, is a chronic pain condition that usually affects one limb, like an arm, leg, hand, or foot. What makes it unusual is the mismatch between the pain and its cause: it’s far more intense and lasts far longer than the original injury would explain.
It often starts after something ordinary, like a sprain, fracture, or surgery. But instead of fading as the body recovers, the pain stays and can even get worse.
The reason is in the nervous system. Normally, pain signals quiet down as an injury heals. With CRPS, the nerves keep firing, and the brain keeps treating the area as a threat long after the tissue has recovered.
The skin can change color or temperature, swell, or become so sensitive that even a light touch feels unbearable, and over time,e it can affect movement too.
CRPS treatment, including steroid injections, can lower inflammation around the affected nerves and ease the pain response. They often create a window of relief that makes other treatments work better.
A local anesthetic is injected near the nerves causing the pain, usually a sympathetic nerve block, which targets the nerves behind CRPS. Nerve block treatment can break the pain cycle and sometimes help calm the nervous system down.
Depending on your case, this might include nerve-pain medications, anti-inflammatories, or drugs that quiet overactive nerves. The goal is to ease pain enough to make recovery and other treatments possible.
One of the most important parts of CPRS treatment. Gentle, steady movement keeps the limb working and helps retrain the nervous system, even when the pain makes it feel counterintuitive.
Managing stress, sleeping well, and staying gently active all support recovery.
There’s no single test that confirms CRPS in Chicago, IL. Because it’s caused by the nervous system rather than by something visible on a scan, diagnosis requires careful evaluation and the exclusion of other causes.
It starts with a conversation and a physical exam. Dr. Tymouch will ask how the pain began, how it’s changed, and if it happened after an injury or surgery. The main clue is that mismatch CRPS is known for – pain far more severe and longer-lasting than the original cause would explain.
Doctors use a set of guidelines called the Budapest Criteria, which involve looking for a specific combination of signs: pain disproportionate to the injury, changes in skin color or temperature, swelling, and movement issues. When enough of these line up and other explanations are ruled out, CRPS becomes the likely diagnosis.
Tests like X-rays, MRIs, or nerve studies may be used. Not to confirm CRPS, but to rule out conditions that mimic it. Complex Regional Pain Syndrome (CRPS) responds better to early treatment.
As soon as you see something isn’t right. There’s no benefit in trying to walk off CRPS; it’s not the kind of pain that fades with time, and waiting usually makes it harder to treat.
The biggest warning sign is pain that doesn’t match the injury: if a sprain, fracture, or surgery has healed, but the pain is still there, or even getting worse, that’s reason enough to get checked. The same goes for unusual changes in the area, such as swelling, changes in skin color or temperature, or a limb that has become extremely sensitive to touch.
CRPS is hard to manage. Dr. Tymouch listens, and with over 20 years spent treating complex nerve pain, he knows how stubborn this condition can be.
Complex Regional Pain Syndrome treatment is built around your body. Depending on your case, that could include nerve blocks, physical therapy, targeted injections, regenerative medicine, or a mix of approaches.

CRPS treatment focuses on reducing pain, improving mobility, and calming the overactive nervous system. Depending on the patient, treatment may include medications, injections, nerve blocks, physical therapy, and lifestyle changes.
CRPS is usually triggered by an injury, surgery, fracture, burn, or nerve damage. The condition develops when the nervous system continues sending pain signals long after the original injury has healed.
There is no single test for CRPS. Diagnosis is based on symptoms, a physical examination, medical history, and the exclusion of other conditions using established guidelines such as the Budapest Criteria.
Common CRPS treatment options include nerve blocks, steroid injections, medications, physical therapy, and lifestyle modifications. The best complex regional pain syndrome treatment plan depends on the severity of symptoms and the individual’s needs.
