Frequently Asked Questions
What strange physical symptoms can anxiety cause?
Anxiety can cause surprising, uncommon symptoms that are often misinterpreted as signs of serious illness. These can affect nearly every system in your body.
Unusual physical symptoms include:
-
Burning skin sensations (without rash)
-
Phantom smells (olfactory hallucinations)
-
Internal vibrations or “body buzzing”
-
Muscle twitching or spasms
-
Electric shock feelings (“brain zaps”)
-
Hot or cold flashes without temperature change
-
Light sensitivity or blurry vision
-
Feeling of a lump in the throat
-
Jaw tightness or facial pressure
-
Tingling in limbs or face
-
Gastrointestinal discomfort like bloating or nausea
Expert Note:
“Anxiety activates your sympathetic nervous system—your body’s built-in alarm system. This flood of adrenaline and cortisol can cause very real and sometimes strange physical sensations,” says Dr. Asha Nduka, MD, a consulting physician with Avena Psychological Services.
Can anxiety cause weird body sensations?
Yes. Anxiety can cause sensations that mimic neurological disorders or chronic illnesses—but are often harmless and temporary.
Examples of odd body sensations:
-
Numbness or tingling in hands, feet, or face
-
Feeling like your body is vibrating inside
-
Feeling detached from your body (depersonalization)
-
Feeling like the world around you isn’t real (derealization)
-
Chest tightness without cardiac cause
-
Muscle weakness or “jelly legs”
-
Rapid heartbeats or skipped beats
-
Trembling or shaky limbs
-
Difficulty swallowing or tight throat
Why it happens:
These symptoms are often linked to hyperventilation, muscle tension, or heightened nervous system arousal caused by anxiety.
How do I know if my symptoms are from anxiety?
You may be experiencing anxiety-related symptoms if:
- They appear or worsen during times of stress or overwhelm
- Medical tests (bloodwork, scans, ECG) come back normal
- Symptoms move around or shift in intensity
- They ease with distraction, relaxation, or deep breathing
- You’re prone to worry or “health anxiety”
Comparison tip:
Anxiety symptoms tend to be episodic, inconsistent, and closely tied to emotional stress. Conditions like MS, epilepsy, or thyroid issues have more stable, consistent physical patterns and usually worsen over time.
Is numbness a symptom of anxiety?
Yes. Numbness is one of the most commonly reported weird physical symptoms of anxiety.
What it feels like:
-
Tingling or pins and needles in the arms, hands, face, or legs
-
A sensation of “dead” or disconnected limbs
-
Cold patches or areas of reduced sensation
-
Comes and goes, especially during or after panic attacks
Cause:
Anxiety-related hyperventilation changes your blood’s CO2 levels, which can temporarily alter nerve function—especially in the extremities.
When to seek emergency care:
If numbness is one-sided, sudden, or comes with slurred speech or confusion, it may signal a stroke or other medical emergency. Always rule out urgent causes first.
What does anxiety feel like physically?
Anxiety can feel like you’re:
-
Having a heart attack
-
About to faint or collapse
-
Losing control of your body
-
On high alert, even when nothing is wrong
-
Trapped inside your own body
Physically, you might notice:
-
Tight chest or shallow breathing
-
Sweaty palms or chills
-
Upset stomach or frequent urination
-
Tense muscles or jaw clenching
-
Dizziness, nausea, or feeling off-balance
-
Sensory sensitivity (light, sound, smell)
Real patient example:
“I felt like my whole body was buzzing—like a live wire under my skin. I thought I had a neurological condition. It turned out to be anxiety.”
