History and Physical Examination

To diagnose itching, the doctor will conduct a physical examination of the skin and ask for details about the symptoms and medical history.

Laboratory Tests

The doctor may recommend certain tests to confirm the diagnosis. These tests help identify whether the itching is due to a primary condition or if it's a symptom of another underlying health issue.

The tests may include:

• Complete Blood Count (CBC): This test can help identify if an internal condition, like anemia, is causing the itch.
• Erythrocyte Sedimentation Rate (ESR): A high ESR can indicate inflammation or infection that may contribute to itchy skin.
• Total IgE Test: This test measures the overall level of immunoglobulin E (IgE) in the blood, indicating an allergic response.
• Specific IgE Test: This measures IgE levels specific to individual allergens, with separate tests conducted for each allergen.
• Allergy Panel: A series of over 29 tests that help identify particular allergens causing reactions such as itching.
• Fasting Glucose: Prolonged high blood sugar levels can result in itchy skin and can also help diagnose conditions like diabetes.
• Liver Function Test (LFT) and Kidney Function Test (KFT): These tests help assess liver or kidney conditions that might lead to itching.
• Blood Urea Nitrogen (BUN): This test measures urea nitrogen levels in the blood and is often done when signs of kidney disease, such as fatigue and itching, are present.
• Thyroid Function Tests: These tests measure thyroid hormone levels, as imbalances can cause skin issues and itching.
• Stool Analysis: This test checks for the presence of parasites, which can sometimes cause itching.

Imaging Tests

Chest CT Scan: A CT scan can provide detailed images and detect conditions, like enlarged lymph nodes, which could be linked to itching.

Skin Biopsy

A skin biopsy involves taking a small sample of skin tissue to examine under a microscope. This can help diagnose skin conditions like psoriasis, eczema, actinic keratosis (precancers), and warts, which can cause itching.

• Drink 8-10 glasses of water daily to keep skin hydrated and supple.
• Use lukewarm water for bathing, limiting shower time to no more than 10 minutes.
• Choose mild, skin-friendly soaps and body washes.
• Moisturize skin regularly, ideally with an unperfumed emollient or moisturizer.
• Wear loose, breathable clothing and avoid tight, synthetic fabrics.
• Always apply sunscreen and wear UV-protective clothing and accessories when outdoors.
• Wash clothes using gentle detergents suitable for sensitive skin.
• Use a humidifier indoors to maintain moisture levels and prevent dry skin.
• Reduce stress, as it can trigger or worsen itching.

Specialists to Consult

Doctors who can help with the diagnosis and treatment of itching include:

• General Physician: A general physician can diagnose and address underlying medical conditions that may be causing itching, offering guidance on managing symptoms.
• Dermatologist: A dermatologist specializes in diagnosing and treating skin-related issues and can provide expert care for itching caused by skin conditions.

The goal of itching treatment is to address the underlying cause while also providing symptomatic relief.

First-Line Treatment

• Apply a cold, wet cloth or ice pack to the affected skin for about 10 minutes to alleviate itching.
• Use moisturizing creams containing ingredients like ceramides, glycerin, aloe, hyaluronic acid, vitamin E, petrolatum, and humectants.
• Apply cooling agents such as menthol or calamine, which can be more effective if kept refrigerated.
• Over-the-counter creams with anti-itch agents like crotamiton can help.
• Mild steroid creams, such as hydrocortisone, are available for short-term use on small, inflamed areas.

If itching persists after first-line treatments, further specific treatment may be recommended based on the underlying cause.

Topical Treatment

Antifungal Creams:

If the itching is caused by a fungal infection, antifungal creams or powders are recommended. Examples include:

• Clotrimazole
• Econazole
• Miconazole
• Fluconazole
• Ketoconazole

Topical Steroids:

Stronger steroid creams may be prescribed for certain conditions but should be used only under medical supervision.

Local Anesthetics:

Used to treat localized neuropathic itching or itching related to chronic kidney disease. Examples include:

• Benzocaine
• Lidocaine
• Polidocanol
• Pramoxine

Topical Calcineurin Inhibitors:

These medications help reduce inflammation and suppress immune responses in the skin, providing relief for conditions like eczema. Examples include:

• Tacrolimus
• Pimecrolimus

Tricyclic Antidepressants:

These are used for chronic and neuropathic itching by blocking specific nerve signals. Doxepin 5% cream is commonly prescribed.

Capsaicin:

Used for localized chronic or neuropathic itching. This cream should be applied regularly for maximum effect.

Systemic Treatment

Antihistamines:

These drugs help relieve itching caused by allergic reactions. Some commonly used antihistamines include:

• Chlorphenamine
• Cinnarizine
• Diphenhydramine
• Hydroxyzine
• Acrivastine
• Cetirizine
• Fexofenadine

Nonsteroidal Anti-Inflammatory Drugs (NSAIDs):

These medications reduce inflammation and provide relief from discomfort. Common examples include:

• Paracetamol
• Ibuprofen

Antidepressants:

Certain selective serotonin reuptake inhibitors (SSRIs) may help alleviate long-term itching. Examples include:

• Fluoxetine
• Sertraline

Anticonvulsants:

These drugs are useful for treating neuropathic itching and itching associated with chronic kidney disease. Examples include:

• Gabapentin
• Pregabalin

Immunosuppressants:

These medications help control or suppress the immune system, breaking the itch-scratch cycle and preventing skin infection. Examples include:

• Cyclosporine A
• Thalidomide

Chronic itching (pruritus) that lasts longer than six weeks can negatively impact your quality of life and lead to the following complications:

• Thickening and hardening of the skin
• Redness and inflammation
• Persistent urge to scratch or pick at the skin
• Deep cuts or tears in the skin
• Scarring
• Skin infections
• Disrupted sleep
• Anxiety and depression

Several alternative treatments may offer relief from itching, but it’s essential to consult your doctor before trying anything new. Some common alternative therapies include:

Light Therapy (Phototherapy):

This therapy involves exposing the skin to specific types of light and is particularly useful for individuals who cannot take oral medications. A series of sessions may be required for effective results.

Homeopathy:

Research suggests that homeopathic treatments can be effective in managing skin rashes and itching.

Traditional Chinese Medicine:

This therapy may offer relief through oral herbal remedies, herbal fumigation, and external washes.

Acupuncture:

In acupuncture, thin needles are inserted into the skin to alleviate symptoms. It is believed to help reduce itching by inhibiting brain activation.

Behavioral Therapy:

This approach is useful for managing itching related to atopic dermatitis. Participants learn techniques to suppress the reflex to scratch through distraction and habit reversal strategies.

Here are some general tips to relieve itching and prevent skin damage caused by scratching:

• Keep your nails clean, short, and smooth to minimize skin damage.
• Instead of scratching, try gently tapping or patting the itchy area.
• Apply a cold compress to the affected area for cooling relief.
• Consider wearing cotton gloves at night to avoid scratching during sleep.
• Avoid alcohol, caffeine, and spicy foods, as they may increase blood flow to the skin and worsen itching.
