You're not going crazy, and there aren't actually bugs crawling on your skin. That creepy, crawly sensation you're experiencing has a name: formication, and it's more common during perimenopause than you might think.
What Is Formication?
Formication is the medical term for the sensation of insects crawling on or under your skin when nothing is actually there. It's a type of paresthesia (abnormal skin sensation) that can feel like:
- Ants or bugs crawling on your arms, legs, or scalp
- Tingling or prickling sensations
- Itching without visible cause
- Feeling like something is moving under your skin
Why Does Perimenopause Cause This?
Estrogen and Nerve Function
Estrogen helps regulate nerve function and skin sensitivity. As levels fluctuate during perimenopause, your nervous system can misinterpret normal sensations.
Stress and Anxiety
Hormonal changes can increase anxiety, which can amplify these sensations and make you more aware of normal skin sensations.
Sleep Disruption
Poor sleep, common in perimenopause, can heighten nerve sensitivity and make these sensations more noticeable.
Other Perimenopause Symptoms You Might Not Connect
If you're experiencing formication, you might also notice:
- Irregular periods
- Brain fog or memory issues
- Mood changes
- Sleep problems
- Hot flashes or night sweats
- Dry, itchy skin
What You Can Do
Rule Out Other Causes
While perimenopause is a common cause, see your doctor to rule out other conditions like diabetes, thyroid issues, or vitamin deficiencies.
Support Your Nervous System
- B-complex vitamins for nerve health
- Magnesium for nerve and muscle function
- Omega-3s for inflammation
- Adaptogenic herbs for stress support
Skin Care
- Use gentle, fragrance-free moisturizers
- Avoid hot showers that can dry skin
- Consider a humidifier
- Wear breathable, natural fabrics
When to See a Doctor
Consult your healthcare provider if:
- Sensations are severe or persistent
- You have visible skin changes
- Symptoms interfere with daily life
- You're experiencing other concerning symptoms
Remember: you're not imagining this, and you're not alone. These sensations are a real symptom that many women experience during hormonal transitions.
