What causes Burning under skin armpit?

Burning under the skin in the armpit can have several possible causes. Here are some common reasons:

1. Skin Irritation: Tight clothing, friction, or certain fabrics can cause skin irritation and a burning sensation. This is often associated with redness, itching, and discomfort in the affected area.

2. Shaving or Waxing: Shaving or waxing the armpit area can cause temporary skin irritation and a burning sensation, especially if the skin is sensitive.

3. Deodorant or Antiperspirant: Some deodorant or antiperspirant products may cause allergic reactions or skin irritation, leading to burning and discomfort. This can happen when your skin is sensitive or if the product contains harsh chemicals or fragrances.

4. Contact Dermatitis: Contact with allergens or irritants, such as certain soaps, detergents, fabrics, jewelry, or other substances, can cause contact dermatitis. This can manifest as a burning sensation, along with redness, itching, and a rash.

5. Ingrown Hairs: Ingrown hairs can occur after shaving or waxing, causing a burning or stinging sensation under the skin. These are often accompanied by small, red bumps or pustules.

6. Folliculitis: Folliculitis refers to the inflammation of hair follicles, often caused by bacterial or fungal infections. This can lead to burning and itching in the affected area, along with small, pus-filled bumps or pimples.

7. Infection: In rare cases, burning under the skin in the armpit may indicate an underlying infection, such as a bacterial or fungal infection. This may require medical evaluation and treatment with appropriate medications.

8. Medical Conditions: Certain medical conditions, such as diabetes, thyroid issues, or nerve damage, can cause a burning sensation in different parts of the body, including the armpits.

If you experience persistent or severe burning under your armpit, it is advisable to consult with a healthcare provider for an accurate diagnosis and appropriate treatment. They can determine the underlying cause and recommend the best course of action to address the discomfort.
