Fibromyalgia is a chronic pain disorder defined by widespread musculoskeletal pain, often accompanied by severe fatigue, sleep disturbances, and cognitive dysfunction known as “fibro fog.” The condition is complex, involving a dysregulation of pain processing that causes significant discomfort and tenderness across the body. For many individuals with Fibromyalgia (FM), the prospect of physical intervention, such as chiropractic care, raises a valid concern. They worry whether therapeutic touch or joint manipulation could unintentionally trigger a symptom flare-up or worsen their baseline pain.
Understanding Fibromyalgia Pain Sensitivity
The potential for physical treatments to exacerbate pain is rooted in the underlying neurobiology of Fibromyalgia, which involves an altered state of the nervous system. This altered state is described as central sensitization, where the central nervous system—the brain and spinal cord—is persistently on high alert. This continuous state of heightened reactivity amplifies sensory input, causing the body to register non-threatening signals as painful. Central sensitization leads to two distinct forms of abnormal pain perception: allodynia and hyperalgesia. Allodynia is the experience of pain from stimuli that should not be painful, such as light pressure. Hyperalgesia is an exaggerated pain response to stimuli that are already painful. Because the nervous system is operating with an amplified pain volume, strong physical input from manual therapy can easily overload the system and result in a symptom flare.
Mechanisms of Potential Exacerbation
The risk of chiropractic care worsening Fibromyalgia symptoms lies mainly in the type and intensity of the physical force applied during the session. Traditional chiropractic adjustments often involve high-velocity, low-amplitude (HVLA) thrusts, which are quick, forceful movements intended to restore joint motion. For a patient with a centrally sensitized nervous system, this intense, sudden input can be perceived as a threat or trauma. This aggressive input can trigger an increase in muscle tension, spasms, and a significant pain flare-up immediately following the session. Furthermore, soft tissue work that is too deep or prolonged can be particularly problematic due to allodynia and hyperalgesia. While some post-treatment soreness is normal, in FM patients, this discomfort is often amplified significantly, leading to a prolonged increase in pain and fatigue that can last for days.
Adapting Chiropractic Care for Fibromyalgia
The approach to chiropractic care for Fibromyalgia must be carefully modified to respect the patient’s heightened pain sensitivity. Instead of traditional forceful techniques, chiropractors use low-force methods that deliver precise, gentle input to the joints and tissues. These gentler adjustments are designed to improve joint mobility and nervous system function without activating the body’s pain alarm system.
Low-Force Adjustment Techniques
Specific low-force techniques, such as the Activator method, use a small, hand-held instrument to deliver a controlled, light impulse to the spine, avoiding the sudden force of a manual thrust. Other gentle options include the use of a segmental drop table, where gravity assists the adjustment, or flexion-distraction therapy, which uses a specialized table to gently stretch the spine. Soft tissue work is also adapted, focusing on gentle massage and myofascial release that avoids deep, painful pressure points. Treatment sessions should be shorter in duration, especially initially, and the frequency should be reduced to allow the patient’s body time to adapt and recover between visits.
Recognizing and Responding to Adverse Reactions
Even with modified, gentle care, a temporary increase in soreness or fatigue may occur as the body adjusts to the treatment. This temporary post-treatment soreness is generally mild and should resolve within 24 to 48 hours, comparable to muscle fatigue felt after a mild workout. A severe flare-up, however, is characterized by a significant, prolonged spike in widespread pain, debilitating fatigue, or muscle spasms that last for several days or more. Immediate and open communication with the chiropractor is paramount if an adverse reaction occurs. Patients must communicate their pain levels and tolerance during the session, and the chiropractor should be responsive and ready to adjust the technique or stop the intervention entirely. If the patient experiences discomfort, they should immediately advocate for a lower-force approach or request a technique change for the next session.
