Introduction to the Condition
Itchy armpits, or itchy skin in the underarm area, are a common and often frustrating problem that can affect anyone. The skin in the armpits is particularly sensitive, making it more prone to irritation and discomfort. Whether the cause is a minor skin condition, an allergic reaction, or a more serious health issue, understanding why your armpits itch is the first step toward finding relief. Itchy armpits can result from a range of factors, including irritated skin, allergies, and underlying health conditions. By learning about the different causes and how they affect the skin, you can take targeted steps to soothe symptoms and restore comfort. In the following sections, we’ll explore how skin conditions, allergies, and health-related issues can contribute to itchy armpits, and what you can do to address them.
What Causes Itching Under Arms at Night?
- Skin irritation: Shaving, friction, or harsh soaps can irritate the sensitive underarm skin, leading to itchy and irritated skin or even a burning sensation.
- Allergic reactions: Deodorants, antiperspirants, laundry detergents, or fabrics may trigger itching and make your armpits itchy.
- Excessive sweating (hyperhidrosis): Moisture creates an environment for irritation and infection, and sweat glands clog can occur, increasing the risk of itchy armpit symptoms.
- Fungal or bacterial infections: Warm, moist armpits are prone to infections like tinea (ringworm) or folliculitis. A fungal infection can cause armpits itchy and may require targeted antifungal treatment to effectively treat itchy armpits [1].
- Skin conditions: Eczema, psoriasis, and contact dermatitis are common culprits [2].
- Chronic skin conditions: Persistent itchy and irritated skin can be caused by chronic skin conditions such as eczema, lupus, or other autoimmune diseases, which may require ongoing management.
- Hormonal changes: Fluctuations during menopause or pregnancy can increase skin sensitivity.
- Systemic diseases and medical conditions: Diabetes, liver, or kidney disease, as well as other medical conditions, can present with nocturnal itching or itchy skin at night.
- Medications: Some drugs, including antibiotics and statins, may cause itching as a side effect.
- Psychological factors: Stress and anxiety can heighten itch perception at night and make you feel itchy.
- Bed bugs or insect bites: Can cause localized itching that worsens at night.
- Risk factors: Age, environmental factors, and personal habits can increase the likelihood of experiencing itchy armpit symptoms.
Nocturnal pruritus (itchy skin at night) can be caused by a combination of these factors. Sweat glands can become clogged, leading to irritation, bumps, and a burning sensation under the arms. Maintaining proper hygiene and treating itchy armpits promptly can help prevent complications such as skin infection. Skin cells release histamine, which can make you feel itchy, so addressing the underlying cause is important to effectively treat itchy armpits.
Identifying the underlying cause is crucial for effective treatment.
Skin Conditions and Itchiness
Many people experience itchy armpits as a result of skin conditions such as atopic dermatitis, eczema, or psoriasis. These conditions can cause dry skin, inflammation, and persistent irritation, leading to uncomfortable itchy sensations in the underarm area. Intertrigo, a rash that develops in skin folds like the armpits, is another common culprit. To relieve itchy skin caused by these conditions, it’s important to keep the skin hydrated by using gentle, fragrance-free moisturizers and cleansers. Applying anti-itch creams or topical steroids, as recommended by a healthcare provider, can help soothe itchy armpits and reduce inflammation. By maintaining a regular skincare routine and addressing dryness, you can help prevent flare-ups and keep your skin comfortable.
Allergies and Itchiness
Allergic reactions are a frequent cause of itchy armpits. Ingredients in personal care products such as deodorants, soaps, or laundry detergents can trigger skin irritation and itchiness, especially in those with sensitive skin. Fragrances, preservatives, and other additives are common allergens that may lead to uncomfortable symptoms. Identifying and avoiding these triggers is key to preventing itchy armpits. In addition, allergic reactions to insect bites or stings can also cause localized itching. To relieve itchy skin and reduce inflammation, try applying cold compresses or soothing aloe vera gel to the affected area. These simple remedies can help calm irritated skin and provide much-needed relief.
Health-Related Causes
In some cases, itchy armpits may signal an underlying health issue that requires medical attention. Conditions such as breast cancer, inflammatory breast cancer, or lymphoma can sometimes present with itching in the armpit area, especially if accompanied by other symptoms like severe pain, skin discoloration, or swelling. Skin infections and nerve disorders are additional health-related causes to consider. If your itchy armpits persist, worsen, or are associated with unusual symptoms, it’s important to consult a healthcare provider for a thorough evaluation. Practicing proper hygiene, avoiding harsh chemicals, and choosing gentle skincare products can help prevent itchy armpits and support overall skin health. Always seek professional advice if you suspect an underlying condition.
Symptoms of Itching Under Arms at Night
- Intense itching, especially in the evening or at bedtime
- Redness, bumps, or rash in the armpit area
- Dry, flaky, or thickened skin
- Burning, stinging, or tenderness
- Scratching that leads to broken skin or sores
- Disturbed sleep or insomnia
- Unpleasant odour (if infection is present)
How Is Nocturnal Pruritus (Underarm Itching) Diagnosed?
Diagnosis starts with a detailed medical history and physical examination. Your clinician may ask about your symptoms, triggers, and any underlying health conditions. They may also inquire about recent or ongoing cancer treatments, as these can be associated with skin symptoms such as itching under the arms. Clinicians will also look for signs of skin infection. Additional tests may include:
- Skin swabs or scrapings for suspected infections
- Patch testing for allergies
- Blood tests to check for diabetes, thyroid, liver, or kidney issues
- Assessment of hygiene and personal care products
Early and accurate diagnosis is essential for effective treatment [3].
Home Remedies and Self-Care
Taking care of your skin at home can make a significant difference in relieving itchy armpits and preventing future discomfort. Start by keeping your skin hydrated with gentle, fragrance-free moisturizers, and use mild cleansers to avoid further irritation. Choose breathable clothing to minimize friction and help control excessive sweating, which can contribute to itchy skin. Practicing good hygiene and steering clear of harsh chemicals in personal care products are essential steps in preventing itchy armpits. If you experience itching, applying anti-itch creams, topical steroids, or cold compresses can help soothe itchy armpits and provide quick relief. Remember, if your symptoms persist or become more severe, it’s important to consult a healthcare provider to rule out any underlying conditions and receive appropriate treatment. By combining self-care with professional guidance, you can effectively manage itchy armpits and maintain healthy, comfortable skin.
Treatments for Itching Under Arms at Night
The best treatment depends on the underlying cause, severity, and your individual needs. Options include:
- Gentle cleansing: Use mild, fragrance-free soap and avoid scrubbing.
- Moisturisers: Apply fragrance-free creams or ointments to prevent dryness.
- Topical steroids: Reduce inflammation in eczema, psoriasis, or allergic reactions.
- Antifungal or antibacterial creams: For infections, as prescribed by your doctor.
- Antihistamines: Oral or topical antihistamines can relieve allergic itching and help with sleep.
- Loose, breathable clothing: Reduces friction and moisture build-up.
- Addressing underlying conditions: Managing diabetes, thyroid, or liver disease can reduce symptoms.
- Behavioural strategies: Stress management, mindfulness, and keeping nails short to prevent skin damage.
Prolotherapy
In recent years, Prolotherapy has built its reputation within the medical community for its clinically proven ability to treat itching under arms.
Published research has proven its pain-relieving, anti-inflammatory and regenerative benefits.
Prolotherapy involves injecting a natural regenerative solution with tiny needles. This has been shown to stimulate the production of collagen cells, the small cells needed to help with itching under arms.
As prolotherapy is helping to treat the root cause of itching under arms, it is deemed to be a permanent fix, preventing the symptoms from returning.
