If you’re battling itchy arms, you’re likely seeking reasons and relief for this distressing symptom. Could it be dry skin, an allergic reaction, or something else? In the following sections, we cut through the confusion to provide clear insights into the causes of itchy arms and ways to soothe your skin without overcomplicating things. The most common cause of itchy arms is a condition called Brachioradial Pruritus. Towards the end of the article we tell you everything you need to know about treatment for this condition.
What Causes Itchy Arms?
Itchy arms can result from a variety of causes, including:
- Nerve irritation (often from the neck, as in brachioradial pruritus)
- Skin conditions like eczema, psoriasis, or contact dermatitis
- Environmental factors such as sun exposure, heat, humidity, or allergens
- Underlying health issues like liver or kidney disease, vitamin deficiencies, or nerve impingement
- Allergic reactions to soaps, fabrics, or foods
- Stress and anxiety (which can worsen symptoms)
The most common cause is brachioradial pruritus, a nerve-related condition often triggered by sun exposure or cervical spine issues.
How to Identify the Cause of Your Itchy Arms
Visual Clues
Look for rashes, blisters, dry or flaky skin, or changes in color or texture. Lichen planus and prurigo are examples of rashes that can cause intense itching.
Associated Symptoms
Systemic symptoms (weight loss, fever, fatigue), joint pain, or abnormal sensations (pain, tingling, stinging) may indicate an underlying health issue. Seek urgent care if you have breathing difficulties or severe allergic reactions.
Triggers and Risk Factors
Age, skin conditions, sun exposure, certain fabrics, foods, or stress can all be triggers. Identifying and avoiding these can help prevent flare-ups.
Effective Treatments for Itchy Arms
Topical Solutions
Over-the-counter hydrocortisone creams can relieve mild itching. Prescription corticosteroids, calcineurin inhibitors (tacrolimus, pimecrolimus), and capsaicin cream may be used for more severe cases. Keep creams refrigerated for extra cooling relief.
Oral Medications
Antihistamines (e.g., diphenhydramine) can help with allergic itching and sleep. For chronic or severe cases, SSRIs (fluoxetine, sertraline) or tricyclic antidepressants (doxepin) may be prescribed. Always use under medical supervision.
Lifestyle Changes and Home Remedies
- Apply fragrance-free moisturizers daily after bathing
- Avoid known irritants and manage stress
- Increase omega-3 fatty acids in your diet
- Use diluted apple cider vinegar or Epsom salt baths
- Use a humidifier and try wet wrap therapy
Regenerative Injection Therapy
Many symptoms of itchy arms are due to brachioradial pruritus, which involves nerve irritation. Regenerative Injection Therapy (RIT) involves injecting a natural solution with fine needles to strengthen and repair the structures around the nerves, allowing irritation to subside.
As RIT treats the root cause of brachioradial pruritus and itchy arms, many people report permanent relief. See a video testimonial here.

Skin Care Routine

- Use warm (not hot) water and mild soap

- Keep nails short and smooth to prevent skin damage from scratching
When to Seek Professional Help for Itchy Arms
Persistent or Severe Symptoms
If itching persists, worsens, or disrupts daily life or sleep, see a healthcare provider. New rashes, bumps, or inflammation also warrant medical attention.
Signs of Infection
Seek immediate care for pus, redness, streaking, or signs of infection (boils, cellulitis, ringworm, MRSA).
Unresponsive to At-Home Treatments
If home remedies and OTC treatments do not help, consult a dermatologist or GP for further evaluation and management.
Summary
Itchy arms can be caused by skin conditions, nerve irritation, allergies, or underlying health issues. Identifying the cause is key to effective treatment. Options include topical and oral medications, lifestyle changes, and advanced therapies like Regenerative Injection Therapy. Prevention and timely medical care are essential for lasting relief.
