Why does my skin feel like it’s crawling? (What is Formication?)

What Is Formication? The 'Crawling Skin' Sensation Explained

Few sensations feel as unnerving as the sudden sense that something is crawling on or under your skin. Even when nothing is there. The medical term for this experience is called formication, and it’s a type of paresthesia (a fancy name for unusual skin sensations that happen without a visible cause). 

In simpler language, the feeling itself is real, but it isn’t coming from an external irritant, rash, or insect bite. And, maybe surprisingly, formication isn’t uncommon during perimenopause and menopause. Some estimates suggest it affects up to 20 percent of women during midlife and tends to feel most severe during late perimenopause. 

In most cases, formication is a benign menopause-related symptom, even if it feels uncomfortable or distressing in the moment. Ahead, we’ll unpack why it happens and what can bring relief.

Why Does Formication Happen During Perimenopause and Menopause?

There’s a lot happening behind the scenes during perimenopause and menopause, and these changes can make some women more prone to formication. One of the biggest drivers is declining estrogen, which plays an important role in both skin health and nerve function.

So what’s actually going on? The answer comes down to how hormonal shifts affect both the skin and the nervous system:

Changes in the Skin 

Estrogen supports the skin’s barrier (the outer layer of the skin), collagen production, and moisture retention. As levels of estrogen fluctuate and decline, skin can become thinner, drier, and more sensitive. 

This increased sensitivity and dryness can make everyday sensations more noticeable and uncomfortable. Enter: those sensations of tingling, itching, or crawling.

Effects on Nerve Signaling

Estrogen also supports the health and stability of the nervous system. Hormonal fluctuations during menopause can change how nerves send and process sensory signals, which may contribute to abnormal sensations like pins-and-needles or the feeling that something is moving across your skin.

Overlapping Menopause Symptoms

Formication can show up alongside other common menopause symptoms, like hot flashes and night sweats. These vasomotor symptoms happen during menopause because shifting estrogen levels can throw off the body’s temperature regulation, leading to sudden waves of heat.

Coming full circle back to formication: Abrupt changes in body temperature, sweating, and skin sensitivity might intensify skin sensations. 

How Formication Relates to Other Menopause Skin and Nerve Symptoms

Formication doesn’t usually happen on its own. As we’ve explored, shifts in hormones can affect the skin and nervous system in multiple ways during perimenopause and menopause. This means unusual sensations often appear alongside other symptoms.

Here’s how formication fits into the broader picture:

• It often happens alongside dryness, itching, and skin sensitivity. As estrogen declines, the skin can become thinner, drier, and more reactive. This may lead to persistent itching, irritation, inflammation, and heightened sensitivity — which can sometimes overlap with or intensify crawling or tingling sensations.

• It could be related to other changes in sensory perception. Hormonal fluctuations during menopause can influence nerve signaling and sensory perception. Both of these things can lead to tingling or crawling skin sensations.

• Certain skin conditions may flare during menopause. Hormonal changes can influence inflammatory skin conditions such as eczema, rosacea, and adult acne. When the skin is already irritated or inflamed, unusual sensations could feel extra pronounced. 

• Some symptoms may feel similar but be localized. For example, vaginal atrophy (also called genitourinary syndrome of menopause) can cause dryness, burning, and itching in the genital area. Though it’s different from formication, the sensations can sometimes be confused or overlap. 

The Role of Stress, Sleep, and Mental Health in Skin Sensations

Understanding the connection between hormones, the nervous system, and emotional health can make these sensations feel less mysterious and more manageable. So it may help to hear how stress, sleep disruptions, and emotional challenges — all of which can crop up during menopause — influence how the body processes physical sensations. 

Whether related to hormonal changes or not, other things that can amplify or influence formication include: 

• Stress and anxiety can heighten body awareness. When stress levels rise, the nervous system becomes more alert and sensitive. This can make normal or mild sensations feel stronger, more noticeable, or harder to ignore — including itchiness, crawling, and tingling feelings.

• Sleep issues can make your nervous system more sensitive. Poor sleep, whether from night sweats, insomnia, or hormonal changes, can make your brain more reactive. In other words, when you’re overtired, your threshold for discomfort can drop. This can, in turn, make sensations and pain feel more intense.

• Mental health shapes how you experience symptoms. Formication itself isn’t simply a symptom of anxiety or depression. But emotional health still influences your perception of sensations. When you’re dealing with constant worrying or low mood, symptoms like skin tingling and itching might feel more overwhelming or harder to manage than usual. 

In general, addressing sleep issues, managing stress, and seeking out emotional support might help lower the intensity and frequency of menopause symptoms (formication included).

When to Seek Medical Advice: Ruling Out Other Causes

Aside from being uncomfortable, formication during menopause is mostly harmless. But there are circumstances that make it worth checking in with a healthcare provider.

For example, if the sensation seems to be getting more intense or is messing with sleep, focus, or daily comfort, seeing a doctor is a good idea. A healthcare provider can help figure out what’s happening and then talk through the best ways to manage it. 

It’s also important to see a healthcare provider if you notice any new rashes, sores, or severe itching. Those symptoms could point to a skin condition rather than hormone-related nerve sensations.

In some cases, formication or similar sensations can be linked to underlying health conditions, like: 

• Diabetes (diabetic neuropathy) 

• Thyroid disorders

• Lymes disease

• Neurological conditions

• Mental health conditions 

As a general rule of thumb, getting the right diagnosis and treatment early on can help you feel better and give you peace of mind. 

Evidence-Based Strategies to Manage Formication and Skin Discomfort

There are several ways to improve comfort and support skin health during perimenopause and menopause. Here are some steps to take: 

1. Support your skin barrier with gentle care. A good skincare routine can go a long way, and what used to work may not anymore. If you aren’t already, use mild, fragrance-free cleansers and opt for a moisturizer designed to hydrate and reduce dryness for sensitive skin. It’s also important to steer clear of known irritants like harsh soaps, hot water, or heavily scented products. 

2. Hydrate and nourish from within. Staying well hydrated, protecting your skin from sun exposure with daily SPF, and eating a nutrient-rich diet (with plenty of antioxidants!) can support skin health and resilience during menopause. 

3. Move your body regularly. Exercise supports circulation and overall well-being. Plus, some promising research suggests exercise could help reduce paresthesia — including sensations like tingling or crawling — in perimenopausal women.

4. Take care of your nervous system. Working on stress management is especially important during this time. Everyone’s different, so it may take some trial and error to see what helps. Incorporating mindfulness meditation, prioritizing sleep, and making time for self-care (whether by doing something you love, talk therapy, or simply relaxing) can boost calmness and lower stress.  

5. Consider medical and hormone-based treatments. For some women, topical estriol or menopause hormone therapy might be helpful, mostly by targeting dryness. In fact, research suggests that topical therapy can help boost skin thickness, hydration, and barrier function. Stubborn cases of itchy skin are also sometimes treated with nerve pain medications like gabapentin, which is also used off-label for hot flashes. 

Many women find the best results come from combining several of these strategies in a way that feels manageable and supportive. A healthcare provider can help determine whether these options are appropriate.
