Anxiety can indeed cause underarm pain through muscle tension, nerve sensitivity, and stress-induced inflammation.
Understanding the Link Between Anxiety and Physical Pain
Anxiety isn’t just a mental or emotional experience—it often manifests physically in surprising ways. One of the lesser-known symptoms is underarm pain. While it might sound unusual at first, there’s a solid biological basis for this connection. Anxiety triggers a cascade of physiological responses that can lead to muscle tightness, nerve irritation, and heightened pain perception.
When anxiety strikes, the body’s fight-or-flight response kicks in. This floods the system with adrenaline and cortisol, hormones that prepare muscles for action. Unfortunately, this readiness often results in prolonged muscle contraction or spasms in areas like the chest, shoulders, and even the underarms. Over time, these tense muscles can cause discomfort or sharp pain beneath the arms.
Nerves running through the armpit area can also become hypersensitive during anxious episodes. This heightened nerve sensitivity amplifies normal sensations into painful ones. In some cases, anxiety may worsen pre-existing conditions like nerve entrapment or inflammation around lymph nodes, further contributing to underarm pain.
How Muscle Tension from Anxiety Causes Underarm Discomfort
Muscle tension is one of the most common physical symptoms linked to anxiety disorders. The muscles around the shoulders and upper chest often bear the brunt of stress-induced tightening. Because these muscle groups connect closely with those in the underarm region, it’s easy for discomfort to radiate into that area as well.
Chronic tension causes muscles to fatigue and develop trigger points—knots of tight muscle fibers that refer pain to other parts of the body. These trigger points can mimic or even mask other conditions by generating localized pain beneath the arms or along the ribcage. If you notice your underarm pain spikes during periods of increased stress or worry, muscle tension may be a key culprit.
Regularly practicing relaxation techniques such as deep breathing exercises, progressive muscle relaxation, or gentle stretching helps reduce this tension significantly. Without intervention, persistent muscle tightness could lead to more severe issues like nerve compression or restricted blood flow in the armpit area.
The Role of Nerves in Anxiety-Related Underarm Pain
The brachial plexus—a network of nerves supplying sensation and movement to your shoulder and arm—passes through your armpit region. Anxiety-induced muscle tightness can compress or irritate these nerves, causing sharp or burning sensations beneath the arm.
Moreover, anxiety heightens your nervous system’s sensitivity overall. This means minor irritations that would normally go unnoticed suddenly feel exaggerated and painful. Nerve hypersensitivity combined with stress-related inflammation can create a perfect storm for persistent underarm discomfort.
In some cases, anxiety may mimic symptoms similar to more serious conditions like heart issues or infections due to nerve-related referred pain patterns in this area—making it crucial to differentiate between anxiety-based pain and other medical problems.
Other Causes of Underarm Pain That Can Be Confused With Anxiety
While anxiety can definitely cause underarm pain through several mechanisms, it’s important not to overlook other potential causes that might require medical attention:
- Lymph Node Swelling: Infection or inflammation often causes swollen lymph nodes in the armpit accompanied by tenderness.
- Muscle Strain: Overuse injuries from exercise or heavy lifting can cause localized soreness.
- Nerve Entrapment: Conditions such as thoracic outlet syndrome compress nerves near the shoulder.
- Skin Conditions: Rashes or infections like folliculitis may produce discomfort.
- Cardiac Issues: Though rare, some heart problems present with referred pain near the left armpit.
If you experience persistent underarm pain alongside fever, swelling, numbness, weakness, or chest discomfort, seek medical evaluation promptly.
Anxiety vs Medical Conditions: When To See a Doctor
Differentiating anxiety-induced underarm pain from other causes is critical but sometimes tricky without professional guidance. Key red flags warranting immediate medical attention include:
- Sudden onset of severe chest or left arm pain
- Dizziness or shortness of breath
- Visible swelling or lumps in armpits
- Numbness or weakness spreading beyond the underarm
- Persistent fever with localized tenderness
For milder but ongoing discomfort without these symptoms, consider consulting your healthcare provider for an accurate diagnosis and tailored treatment plan.
The Science Behind Stress-Induced Inflammation and Pain Sensitivity
Stress hormones released during anxiety episodes don’t just tighten muscles—they also influence immune function and inflammation levels throughout your body.
Cortisol plays a complex role: short-term spikes help manage acute stress but prolonged elevation disrupts immune regulation. This imbalance promotes low-grade inflammation that sensitizes nerve endings and amplifies pain signals.
Research shows people with anxiety disorders often have higher circulating inflammatory markers such as cytokines—proteins that mediate immune responses—which correlate with increased reports of physical symptoms including musculoskeletal pains.
This inflammatory state explains why some individuals feel widespread aches during anxious periods rather than isolated discomfort.
The Impact on Daily Life and Coping Strategies
Underarm pain caused by anxiety can interfere with simple activities like lifting objects, dressing comfortably, or even sleeping on one side without discomfort.
Understanding this connection empowers sufferers to adopt effective coping strategies:
- Mental Health Support: Cognitive-behavioral therapy (CBT) helps manage anxious thoughts reducing physical symptom flare-ups.
- Pain Management: Applying heat packs relaxes tense muscles; gentle massage eases trigger points.
- Lifestyle Adjustments: Regular exercise boosts endorphins lowering overall stress levels.
- Meditation & Mindfulness: These techniques calm nervous system hyperactivity reducing nerve sensitivity.
- Adequate Sleep: Restorative sleep repairs tissue damage caused by chronic tension and inflammation.
Combining psychological care with physical self-care creates a balanced approach that addresses both mind and body aspects of anxiety-related underarm pain.

| Nerve Entrapment (Thoracic Outlet Syndrome) | Numbness/tingling down arm; weakness; aggravated by arm movement; | Surgical consultation; physical therapy; posture correction; |
| Muscle Strain/Injury | Pain worsened by movement; localized soreness/tenderness; | Rest; ice/heat application; NSAIDs; |
| Cardiac-Related Referred Pain (Rare) | Pain radiating from chest to left arm/armpit; shortness of breath; sweating; | Emergency cardiac care; |
The Role of Hormones in Anxiety-Related Physical Symptoms Including Underarm Pain
Hormones don’t just affect mood—they play a massive role in how our bodies respond physically during anxiety episodes.
Adrenaline surges increase heart rate and blood flow but also constrict smaller blood vessels causing ischemic-like sensations (lack of oxygen) around muscles including those near your armpits.
Meanwhile cortisol’s immunomodulatory effects exacerbate tissue sensitivity leading to heightened awareness of discomfort previously unnoticed.
These hormonal shifts explain why anxious individuals often report fluctuating intensity levels in their bodily aches depending on their mental state at any given moment.
The Importance of Recognizing Psychosomatic Symptoms Without Dismissing Them
Sometimes people dismiss symptoms stemming from anxiety as “all in your head,” but this couldn’t be further from reality.
Psychosomatic symptoms are very real physical manifestations triggered by emotional distress—not imaginary pains designed to mislead anyone.
Recognizing that anxiety can produce tangible bodily effects including underarm pain validates sufferers’ experiences while opening doors for comprehensive treatment strategies addressing both mind and body health simultaneously.
