Introduction
Itching on the inner side of the armpit and arm in patients with urticaria may be caused by clothing irritation, emotional stress, food allergies, drug allergies, or worsening of urticaria, requiring targeted management. It is recommended to seek medical attention promptly. The skin affected by urticaria is usually fragile; wearing clothes made of coarse materials may irritate the skin, leading to itching on the inner side of the armpit and arm.

Generally, itching on the inner side of the arm under the armpit due to urticaria may be caused by clothing irritation, emotional stress, food allergies, drug allergies, or worsening of urticaria, and targeted treatments are required. It is recommended to seek medical attention promptly for diagnosis and treatment. Specific analysis is as follows:

1. Clothing Irritation

Skin affected by urticaria is typically more sensitive. Wearing clothes made of coarse materials may irritate the skin, causing itching on the inner side of the arm under the armpit. Choosing breathable, soft clothing may help reduce irritation.

2. Emotional Stress

Urticaria is closely related to emotions and stress. Stress and anxiety may trigger immune system responses, exacerbating itchiness. It is important to manage stress and prevent symptom worsening.

3. Food Allergy

Patients with urticaria may have allergic reactions to certain foods, leading to localized skin symptoms such as itching and redness. Common food allergens include nuts, seafood, and milk. Avoiding these foods may help alleviate symptoms. According to a doctor's advice, medications such as cetirizine hydrochloride oral solution, promethazine hydrochloride tablets, and ketotifen fumarate capsules can be used to relieve symptoms.

4. Drug Allergy

Patients with urticaria may be allergic to certain medications, resulting in localized or systemic itching. If the patient is currently taking medication, it may be necessary to consult a doctor about whether a change in medication is needed.

5. Worsening Urticaria

Flare-ups of urticaria may cause local skin inflammation and itching. Therefore, if the patient is experiencing an active phase of urticaria, itching may intensify. It is recommended to follow medical advice and use medications such as compound beclomethasone and camphor cream, Efu Kang lotion, or calamine lotion to alleviate symptoms.

In daily life, maintaining a light diet and drinking plenty of water can help restore skin health.

Can vigorous scrubbing during bathing cause hives?
Whether vigorous scrubbing during bathing causes urticaria depends on the condition of the skin and the method of scrubbing. It usually does not trigger urticaria if the skin is healthy and the scrubbing is moderate. However, if the skin is sensitive or the scrubbing is too harsh, it may induce urticaria. For daily care, it's important to choose soft bathing tools, control the pressure and frequency of scrubbing, and avoid frequent use of strongly alkaline cleansers.
