[37F] Experiencing persistent armpit itching and burning

What might be happening

Based on the symptoms you've described, here are a few possible explanations:

• Contact Dermatitis: This is a common skin reaction that occurs when your skin comes into contact with an irritant or allergen. Even though you haven't changed your deodorant or other products, it's possible that a new sensitivity has developed. Contact dermatitis can cause redness, itching, and burning sensations.

  • Treatment typically involves identifying and avoiding the irritant. Over-the-counter hydrocortisone cream or antihistamines may help alleviate symptoms.

• Intertrigo: This is a rash that occurs in warm, moist areas of the body, such as the armpits. It can be caused by friction, heat, and moisture, and is often accompanied by redness and itching.

  • Keeping the area dry and using barrier creams or antifungal powders can help. If a secondary infection is suspected, a healthcare provider may prescribe topical or oral medications.

• Fungal Infection: The armpits are a common site for fungal infections due to moisture and warmth. These infections can cause redness, itching, and a burning sensation.

  • Antifungal creams or powders are typically used to treat fungal infections. It's important to keep the area clean and dry.

What you can do

While it's important to consult a healthcare provider for a formal diagnosis, here are some steps you can take in the meantime:

1. Keep the Area Dry: Moisture can exacerbate symptoms, so try to keep your armpits dry. You might consider using a talc-free powder to absorb moisture.

2. Avoid Irritants: Even if you haven't changed products, consider switching to hypoallergenic or fragrance-free options to see if it helps.

3. Use Over-the-Counter Treatments: You can try applying a mild hydrocortisone cream to reduce inflammation and itching. Antifungal creams may also be helpful if a fungal infection is suspected.

4. Monitor Your Symptoms: Use MDandMe to journal your symptoms, track any changes, and note any potential triggers. This information can be valuable for your healthcare provider.

What you should look out for

Seek medical attention if you experience any of the following:

• The rash spreads or worsens despite home treatment.
• You develop signs of infection, such as pus, increased pain, or fever.
• The symptoms persist for more than a week without improvement.

Remember, while these suggestions can help manage symptoms, it's important to consult a healthcare professional for a proper diagnosis and treatment plan.
