Symptoms of Rash on Wrist

A rash on your wrist can appear alone and disappear in a matter of days, or it can present with a host of other symptoms. The symptoms you experience are determined by the underlying condition at the root of your rash. The following symptoms may be associated with a rash on your wrist:

• Itchy wrist (pruritus)
• Pain
• Bumps
• Fluid-filled blisters that may ooze pus
• Warmth in the area of the rash
• Scaly skin changes
• Discoloration and scarring
• Skin cracking and dryness 

Causes of Rash on Wrist

The following conditions may cause a rash to develop on your wrist:

• Allergic or irritant dermatitis: A localized allergic or irritant reaction to substances like fragrances, lotions, latex, poison ivy, or a metal bracelet or jewelry (especially nickel or cobalt) commonly causes an itchy wrist rash. Leather or plastic watchbands or wristbands may also provoke a reaction.
• Dry skin: Dry skin can happen anywhere on the body and is a common cause of itchy skin.
• Eczema: Eczema is a chronic condition causing an itchy rash. It can appear in many places on the body, including the hands or wrists.
• Scabies: Scabies mites have a predilection (preference) to burrow in skin folds (i.e., between the fingers and around the wrist), producing an itchy rash.
• Ringworm: Also known as tinea manuum, ringworm of the wrist is a fungal skin infection that causes a circular or ring-like rash on the hands and wrist.
• Psoriasis: Psoriasis is an autoimmune skin condition that affects the entire body. It may be found as thick, scaly patches or rashes that are itchy and painful to live with. 

How to Treat Rash on Wrist

Most rashes on the wrist are localized and may be treated with topical over-the-counter (OTC) creams and ointments such as hydrocortisone cream and calamine lotion.

Oral antihistamines, like Allegra (fexofenadine), Claritin (loratadine), or Zyrtec (cetirizine), are first-line OTC systemic (body-wide) medications for an itchy rash. However, resolving your underlying medical condition is the most definitive way to eliminate your rash.

If your wrist rash is associated with dry skin, applying a dermatologist-approved moisturizer may provide you with some relief.

Wrist rashes due to contact dermatitis or other skin conditions may also be associated with inflammation and swelling of the wrist, which may be soothed using ice or a cold compress. Identifying the trigger of the reaction and avoiding it can also prevent the rash from continuing or worsening.

Complications Associated With Rash on Wrist

Any rash increases your chance of developing a skin infection because it may itch, causing you to scratch, break the skin, and allow in bacteria. Often, these bacterial infections remain localized and can be treated successfully with topical antibiotics.

Are There Tests to Diagnose the Cause of Rash on Wrist

In most cases, no test is needed to formally diagnose your wrist rash. Your healthcare provider will make a diagnosis after a thorough clinical evaluation and physical examination.

In more severe cases, you may be referred to a dermatologist (a specialist in treating skin conditions). If an allergic reaction is suspected, allergy skin testing may be suggested, although the culprit for your rash may be deduced from a detailed clinical history. For some rashes, a skin scraping or biopsy may be taken for examination.

Some questions your healthcare provider may ask you include the following:

• How long have you experienced this rash on your wrist?
• Do you have this rash in other places on your body?
• Have you had this rash before?
• Have you used a new detergent, soap, or fragrance recently (in the past two weeks)?
• What are your allergies, if any?
• Do you use a daily moisturizer? 

When to See a Healthcare Provider

If the rash on your wrist is associated with fever or severe pain or does not improve within two weeks of OTC treatment, consult a healthcare professional. Most of the time, a rash on your wrist is not indicative of a medical emergency, but it may signify an underlying medical complication.

In moderate or severe cases, you may need a referral to a dermatologist to determine the cause of your rash. 

Allergic reactions can progress from local irritation to a system-wide reaction. If you experience swelling of the mouth or throat or difficulty breathing, you may be experiencing anaphylaxis, a medical emergency, and should seek immediate medical attention and call 911.

Summary

Rashes can occur anywhere on the body, but when they develop on the wrists, you can point to common culprits, like dry skin or an allergic or irritant reaction. It may also be caused by scabies or ringworm.

Depending on the cause, a rash on the wrist may be treated by moisturizing dry skin, treating the rash with OTC hydrocortisone cream, and avoiding possible irritants and allergy triggers. If the rash is severe, accompanied by other symptoms, or doesn't clear up, consult a healthcare provider.

A Word From Verywell

Most skin rashes on the wrist are benign and will go away on their own, but if they don't, check in with a healthcare provider to determine any underlying health conditions.
