8 Uncommon Signs of Inflammation: What Your Body Might Be Telling You
Subtle shifts in energy, skin, and digestion can hint at a hidden health threat.
8 Uncommon Signs of Inflammation You Should Never Ignore
When most people think about inflammation, images of sprained ankles, fever, and redness often come to mind. These classic symptoms are part of acute, short-lived inflammation—a healthy response essential for recovery. But inflammation isn’t just about injury and localized swelling: it can affect your entire system, often subtly, and may persist for months or even years. Chronic inflammation is now connected to a wide range of health conditions, so recognizing its surprising symptoms can be critical.
What Is Inflammation?
Inflammation is your body’s response to injury, infection, allergens, or irritation. It helps you heal and restore balance, or homeostasis. Acute inflammation (think swollen, red skin after a sprain) is usually short-lived and beneficial. However, if inflammatory processes continue unabated, disease development may follow. Chronic inflammation has been linked to conditions such as diabetes, obesity, autoimmune disorders, and heart disease.
Priya Jaisinghani, M.D., clinical assistant professor in the Holman Division of Endocrinology, Diabetes and Metabolism at NYU Langone Health, describes inflammation as “one of the body’s key mechanisms for maintaining homeostasis.” Chronic inflammation may become systemic, affecting multiple body parts and manifesting in a wide array of symptoms.
- Acute inflammation: Short-lived, visible (redness, heat, swelling, pain), healing response to injury or infection.
- Chronic inflammation: Persistent, may be silent, can harm organs and tissues over time and is tied to long-term illnesses.
Chronic inflammation may linger after the initial threat is gone, leading the body to attack its own tissues and eventually contributing to conditions like autoimmune disease, cardiovascular disease, cancer, stroke, and more.
Unexpected Signs of Inflammation
The body’s inflammatory response is designed to protect, but when it goes on too long, it can do harm. Chronic inflammation can affect almost every organ and system, so symptoms may appear far outside the usual redness and swelling. Here are eight unexpected signs of inflammation:
1. Rashes and Skin Changes
Your skin acts as a window into your overall health. Inflammation may manifest as:
- Redness or discoloration
- Itchiness and plaques
- Flaky, dry patches
- Bumps or blisters
- Scabs or rough areas
Conditions like psoriasis, eczema, hidradenitis suppurativa, and scleroderma are fueled by underlying inflammation. These signs are not purely cosmetic: they reflect deeper immune activity and chronic systemic issues.
| Skin Condition | Common Signs | Related to Inflammation? |
|---|---|---|
| Psoriasis | Red, scaly plaques | Yes |
| Eczema | Flaking, itchiness | Yes |
| Hidradenitis Suppurativa | Bumps, abscesses | Yes |
| Scleroderma | Thickened, hard skin | Yes |
2. Persistent Fatigue
If you’re always tired—even after adequate sleep, managing stress, and healthy habits—chronic inflammation could be quietly draining your energy reserves. Research shows that low-grade inflammation disrupts the body’s energy balance, leading to fatigue that doesn’t improve with rest.
What others are reading
- Unexplained exhaustion
- Lack of motivation
- Difficulty concentrating
- Physical weakness
This tiredness may persist for months, and is often overlooked or attributed to busy lifestyles.
3. Problems with Balance
Frequent falls or trouble staying steady might seem unrelated to inflammation, but studies have discovered that higher levels of certain inflammatory markers correlate with problems maintaining balance.
- Dizziness
- Frequent stumbling or falling
- Unsteady walking
- Difficulty orienting in space
Various body systems—including muscles, bones, brain, and inner ear—work together to keep you upright. Inflammation affecting any one of these can result in poor balance.
4. Muscle Weakness
Muscle weakness isn’t just a sign of aging or lack of exercise—it may indicate chronic inflammatory activity targeting your muscles or nerves. Inflammation can diminish muscle strength by:
- Interrupting nerve signals
- Causing direct damage to muscles
- Triggering autoimmune reactions
This weakness may make daily activities more difficult, such as rising from a chair, lifting grocery bags, or climbing stairs.
5. Cognitive Issues
“Brain fog,” memory problems, or difficulty focusing may have inflammation as a root cause. Chronic inflammation can alter brain chemistry and impair nerve signaling.
- Forgetfulness
- Difficulty concentrating
- Mental fatigue
- Problems processing information
Emerging research shows that inflammation is linked to cognitive decline, Alzheimer’s disease, and other neurodegenerative conditions.
6. Dry Eyes
Uncomfortable, gritty, or burning eyes can signal systemic inflammation impacting tear production or gland function. Chronic inflammatory disorders like Sjögren’s syndrome often begin with dry eyes that do not respond to standard eye drops.
- Persistent dryness
- Sensitivity to light
- Scratchy or burning sensation
- Redness or swelling in the eyes
7. Back Pain
If you suffer from persistent back pain, especially without clear injury, inflammation may be a contributing factor. Autoimmune and inflammatory conditions such as ankylosing spondylitis frequently begin with subtle back discomfort.
- Aching or stiffness in the lower back
- Pain that improves with movement
- Morning stiffness or pain
- Gradual progression rather than sudden onset
While non-inflammatory issues like osteoarthritis can also cause pain, back pain accompanied by other systemic symptoms should be evaluated by a healthcare provider.
8. Digestive Issues: Diarrhea
Chronic diarrhea or sudden changes in bowel habits may point to inflammatory activity in the digestive tract. Conditions such as inflammatory bowel disease (IBD), including Crohn’s disease and ulcerative colitis, stem from misdirected immune attacks in the gut lining.
- Loose or frequent stools
- Abdominal pain
- Cramps
- Blood or mucus in stools
- Unexpected weight loss
Such symptoms should not be ignored as they often indicate a medical issue in need of proper diagnosis and management.
Why Is Chronic Inflammation Dangerous?
Acute inflammation may help you heal. Chronic inflammation, however, can damage healthy cells and contribute to long-term illnesses—sometimes without clear external signs. Five of the leading causes of death in the United States are linked to chronic inflammation:
- Alzheimer’s disease and other forms of dementia
- Cancer
- Heart disease
- Stroke
- Type 2 diabetes
Other conditions, such as allergies, asthma, acne, eczema, arthritis, and autoimmune disorders (multiple sclerosis, lupus, Sjögren’s syndrome), have also been tied to excessive or misdirected inflammatory responses.
How Is Inflammation Diagnosed?
Diagnosing chronic inflammation can be challenging. Blood tests may check for certain markers:
- C-reactive protein (CRP): Indicates ongoing inflammation.
- Erythrocyte sedimentation rate (ESR): Measures inflammation level.
- Platelet count: May rise during chronic inflammation.
- Albumin levels: Can fall with ongoing inflammation.
- Anemia of chronic inflammation: Low red blood cell counts.
Physical exams may reveal rashes or joint swelling. Providers turn to these clues and, when needed, further diagnostic scans or specialist consultations.
Managing and Preventing Inflammation
If you suspect chronic inflammation, early intervention can safeguard your health and prevent long-term complications. Strategies may include:
- Seeking medical assessment for persistent, unexplained symptoms
- Maintaining a healthy weight
- Physical activity and regular exercise
- Managing stress effectively
- Prioritizing anti-inflammatory foods such as berries, leafy greens, fatty fish, olive oil, and nuts
- Limiting consumption of processed foods, excess sugar, and trans fats
- Managing underlying conditions such as autoimmune diseases or infections
It’s important to avoid self-diagnosis—many symptoms of chronic inflammation overlap with other common health problems. Visit your healthcare provider for a professional assessment if you’re concerned about any of these subtle warning signs.
