Underarm Itching During Coughing or Cold Symptoms

Itchy throat, cough, or during a cold, there is itching in the subcutaneous layer of the armpit?

Hello Doctor: This issue has been bothering me for a long time.
Whenever I have a scratchy throat, cough, or cold, the skin underneath my right armpit becomes itchy.
Each time I ask a doctor, I receive different answers.
Recently, I was told that it might be related to the bronchial area (or related structures), which could be causing the itchiness.
I would like to know which specialty I should consult for similar issues and what kind of examinations I should undergo.
Thank you.

More Info

Underarm itching during coughing or cold symptoms can be a perplexing issue, and it’s understandable that you’re seeking clarity on this matter. The sensation of itching in the underarm area, particularly when accompanied by respiratory symptoms like coughing or a cold, can be attributed to several potential causes.
Firstly, it’s important to recognize that the body’s response to respiratory infections, such as colds or bronchitis, can lead to various systemic reactions. When you cough or experience throat irritation, your body may release histamines and other inflammatory mediators as part of the immune response. This release can sometimes cause localized itching or irritation in areas such as the underarms, which may be more sensitive due to the proximity of lymph nodes and other immune-related tissues.

Another possible explanation for the itching could be related to skin irritation or allergic reactions. If you are using any topical medications, ointments, or even laundry detergents that may come into contact with your underarm area, these could trigger an allergic response, leading to itching. Additionally, if you are sweating more due to illness or fever, this can exacerbate skin irritation and lead to itching.

In some cases, the itching could be a sign of a more systemic issue, such as eczema or another dermatological condition that may flare up during times of stress or illness. It’s also worth noting that certain respiratory conditions can lead to referred sensations in other parts of the body, including the skin.

Given the complexity of your symptoms and the varying opinions you’ve received from different healthcare providers, it would be advisable to consult with a specialist who can provide a thorough evaluation. A dermatologist would be an excellent choice, as they can assess the skin directly and determine if there are any underlying dermatological conditions contributing to your symptoms. They may perform a physical examination and possibly conduct allergy testing if they suspect an allergic reaction.

Additionally, an allergist could also be consulted if there is a suspicion that your symptoms are related to an allergic response. They can perform specific tests to identify potential allergens that may be causing your symptoms.

In summary, while underarm itching during coughing or cold symptoms can be attributed to various factors, including immune responses, skin irritation, or allergic reactions, it is essential to seek a comprehensive evaluation from a dermatologist or allergist. They can provide targeted testing and treatment options to help alleviate your symptoms and address any underlying conditions. In the meantime, consider monitoring any potential triggers, such as new products or changes in your environment, that may coincide with the onset of your itching.
