If you are injured in a car accident, and develop symptoms of fibromyalgia, you may find is difficult to prove that the accident is the cause.

Fibromyalgia is a medical condition that causes a person to suffer widespread musculoskeletal pain. The condition affects the way the brain processes the pain signals, and amplifies painful sensations. The symptoms commonly begin after a traumatic event such as physical trauma caused by a car accident. Unfortunately, there is no cure for fibromyalgia, and it takes significant toll on the patient’s life.
If you were involved in a Chicago car accident, you may be wondering if your recently diagnosed fibromyalgia is related to an injury. Or if your fibromyalgia has gotten worse, is it from being involved in the auto accident?
What Is Fibromyalgia and How Is It Related to Car Accidents?
Fibromyalgia is a chronic disorder characterized by widespread pain, fatigue, sleep disturbances, and cognitive difficulties (“fibro fog”). While the exact cause is not fully understood, strong evidence shows that physical trauma, like that of a car accident, can trigger fibromyalgia in people who may be predisposed. Traumatic injuries, especially those involving the neck such as whiplash, can make a person 13 times more likely to develop fibromyalgia compared to the general population.
Real-World Scenario:
After a rear-end collision on the Kennedy Expressway, a Chicago woman initially walked away with what seemed like minor injuries. Weeks later, she developed chronic pain, muscle aches, and fatigue—a classic progression to post-traumatic fibromyalgia. Her life was disrupted, her work suffered, and she was left fighting for both a diagnosis and just compensation.
Many types of trauma can lead to fibromyalgia. It is believed that neck and head trauma is more likely to trigger the condition. Post-Traumatic Stress Disorder also increases the risk of fibromyalgia. Car accident victims who suffer head and neck injuries in a car accident and later develop PTSD are at a higher risk of developing fibromyalgia.
The condition is very difficult to diagnose. Earlier, a tender point exam was conducted to check pain at 18 different points in the body, but now a patient is considered to have fibromyalgia if they have unexplained and widespread pain lasting at least three months. Often times, the condition is not diagnosed for months or even years after the crash that triggered it.
Chicago and Illinois Car Accident & Fibromyalgia Statistics
-
Illinois sees over 100,000 car crashes each year—with thousands resulting in serious or chronic injuries.
-
Studies have shown car accident trauma is a well-established trigger of fibromyalgia symptoms and diagnosis.
-
Patients with a fibromyalgia diagnosis are more than twice as likely to be involved in a severe car crash compared to the general population, highlighting the risks associated with the condition.
Common Symptoms of Fibromyalgia
Victims of car accident who suffer from fibromyalgia may experience the following symptoms:
- Dull and constant widespread pain
- Extreme fatigue despite sleeping for long periods of time
- Cognitive impairment or “fibro fog” that affects the ability to concentrate
- Headaches
- Pain in the lower abdomen
- Depression
Fibromyalgia is incurable, so the treatment focuses on managing the symptoms. The patients are often prescribe pain relievers to help reduce discomfort and antidepressants to fight fatigue and other related symptoms. Some anti-seizure drugs are also known to be successful in reducing pains associated with fibromyalgia. Patients of fibromyalgia are also provided counseling to learn how to manage the stress associated with fibromyalgia.
Fibromyalgia requires lifetime of care and treatment, because the condition is incurable so the medical costs are often very high. These medical costs should be covered by a settlement or jury verdict in a car accident claim. However, this can happen only when the car accident victim is properly diagnosed. It is important for car accident victims to keep in mind that fibromyalgia symptoms do not usually show up immediately, so they should not settle their case until the full extent of injuries is known.
Chicago Laws on Fibromyalgia-Related Injuries After a Car Accident
Fibromyalgia, if proven to be triggered or worsened by a car accident, can be recognized as a compensable injury under Illinois personal injury law:
-
“Eggshell Skull Rule”: Illinois law states that if an accident aggravated a pre-existing condition such as fibromyalgia, the at-fault driver is still liable for the injury’s full impact.
-
Workers’ Compensation & Accidents: Chicago courts and the Illinois Industrial Commission have affirmed that fibromyalgia can be a compensable work- or accident-related injury if it is disabling and connected to the traumatic incident.
-
Statute of Limitations: Victims generally have 2 years from the date of the accident to file a personal injury claim in Illinois.
Fibromyalgia Car Accident Liability Laws in Chicago
Liability for fibromyalgia in a car accident claim falls under these key rules:
-
Proving Causation: The injured person must show, through medical records and expert testimony, that the car accident likely triggered or aggravated their fibromyalgia.
-
Comparative Fault: If both drivers share blame, Illinois allows recovery as long as the claimant is less than 50% at fault.
-
Insurance Challenges: Insurers often push back on fibromyalgia claims, disputing whether the accident actually caused the condition or arguing its symptoms were pre-existing. Proving your case requires meticulous documentation and advocacy.
Compensation Laws: What Chicago Victims Can Claim
Car accident victims in Chicago with fibromyalgia linked to their crash may pursue compensation for:
-
Medical bills: Chronic pain management, specialist visits, therapy, and medications.
-
Lost wages and diminished earning capacity—fibromyalgia can be severely disabling.
-
Pain and suffering: Both physical and emotional suffering may be recoverable.
-
Future costs: Compensation for future care, medical expenses, or loss of quality of life.
Example: Settlement values can be significant. In one notable case, a fibromyalgia victim originally offered $34,000 ultimately secured a $245,000 settlement after aggressive legal representation.
