Pain is one of the most underrecognized yet impactful symptoms of multiple sclerosis (MS). While the condition is often associated with numbness or mobility issues, research shows that more than 50–70% of people with MS experience pain during the course of their illness — and in many cases, it can become chronic.
Yet MS pain remains widely misunderstood — not only in where it occurs, but in how it feels, why it happens, and how it changes over time.
Why MS Causes Pain
MS targets the central nervous system (CNS) — the brain and spinal cord. When the immune system mistakenly attacks the myelin sheath (the protective coating around nerve fibers), it disrupts normal nerve signaling. Depending on where these lesions occur and how they affect communication between nerves, different types of pain can emerge.
The three most common categories of MS-related pain include:
Neuropathic pain: Directly caused by nerve damage, this can feel like burning, stabbing, tingling, or electric shock-like sensations. It may occur spontaneously or be triggered by touch, temperature, or movement.
Musculoskeletal (nociceptive) pain: Indirect pain resulting from poor posture, spasticity, or altered gait. Muscle stiffness, joint discomfort, and soreness often fall into this category.
Referred pain: Pain that appears in one area due to a problem elsewhere. For instance, limping may lead to lower back or hip pain due to uneven strain on muscles and joints.
Unusual Places MS Pain May Show Up
Unlike localized injuries, MS pain is often unpredictable. It may appear in areas that seem unrelated to disease activity:
Face or jaw: Severe, stabbing pain (often from trigeminal neuralgia) can be one of the earliest or most intense MS symptoms.
Chest or ribs: A tightening or squeezing sensation — known as the “MS hug” — occurs when intercostal muscles between the ribs go into spasm.
Lower back: Strain can result from muscle weakness, poor core stability, or long-term compensation for altered walking mechanics.
Neck and shoulders: These areas often carry tension related to fatigue, poor posture, or imbalance.
Head: Some people with MS report frequent headaches, possibly linked to neck muscle tension or central nervous system dysregulation.
These patterns make it difficult to explain or localize pain — especially when standard tests don’t show inflammation or visible lesions in those areas.
Pain Can Vary Day to Day — Why?
Pain in MS isn’t static. It can fluctuate depending on internal and external factors:
Temperature sensitivity: Heat exposure can worsen nerve conduction issues, making pain feel sharper or more widespread (a phenomenon known as Uhthoff’s phenomenon).
Fatigue: As physical and cognitive energy drains throughout the day, the brain’s ability to regulate discomfort often weakens.
Stress and anxiety: Emotional strain can amplify how the nervous system processes pain, sometimes increasing muscle tension and pain sensitivity.
Sleep disruption: Poor-quality or fragmented sleep reduces your pain threshold and increases inflammation, worsening symptoms over time.
Evidence-Based Ways to Manage MS Pain
Pain management in MS is highly individualized, but several approaches have scientific backing:
1. Physical strategies:
Gentle movement and stretching reduce stiffness and prevent secondary musculoskeletal strain.
Posture and gait training (via physical therapy) can address alignment issues and reduce compensatory pain.
Cooling interventions like cold packs, vests, or fans help those with heat-sensitive neuropathic pain.
2. Medications (under medical guidance):
Anticonvulsants (e.g., gabapentin, pregabalin)
Antidepressants (e.g., amitriptyline, duloxetine) for nerve pain
Muscle relaxants or anti-spasticity agents (e.g., baclofen, tizanidine)
3. Mind-body and behavioral tools:
Mindfulness meditation, which has been shown to reduce pain perception by altering how the brain processes discomfort.
Cognitive-behavioral therapy (CBT) to help reframe pain experiences and reduce psychological stress.
Biofeedback and breathing techniques to regulate the body’s stress-pain response loop.
Takeaway
MS pain is real — even when invisible, inconsistent, or difficult to describe. It may arise from damaged nerves, altered biomechanics, or systemic factors like heat and fatigue. Understanding its many faces is key to reducing its impact on daily life.
If you’re experiencing pain that’s hard to explain, you’re not alone — and it’s worth talking to your care team. The goal isn’t just to “live with it,” but to manage it with tools that work for you.
