Red spots appearing on the inner skin of the biceps

Red spots appearing on the inner side of the biceps skin may be caused by folliculitis, rashes, capillary dilation, urticaria, or allergic reactions. Treatment methods vary depending on the specific condition. Detailed analysis is as follows:

1. Folliculitis

Folliculitis is an infection and inflammation around hair follicles, usually caused by bacteria. If red spots on the inner side of the biceps are accompanied by pain, swelling, and pus discharge, it may indicate folliculitis. Patients are advised to take medications such as cefuroxime axetil tablets or cefdinir tablets as directed by a physician.

2. Rash

A rash refers to abnormal red patches or lesions on the skin, which may result from allergic reactions, infections, or other diseases. If red spots on the inner biceps are associated with itching, flaking, or other skin symptoms, they may be due to a rash. Oral antihistamines such as levocetirizine hydrochloride tablets or chlorpheniramine maleate tablets may be taken under medical guidance.

3. Capillary Dilation

Capillary dilation refers to visible skin abnormalities caused by the expansion and congestion of small blood vessels. If the red spots on the inner biceps appear as a fine network of blood vessels, this may indicate capillary dilation. Treatments typically include laser therapy, electrocoagulation, or other procedures aimed at constricting blood vessels.

4. Urticaria

Urticaria commonly presents as red, raised plaques accompanied by intense itching. If the red spots appear as irregularly shaped patches, urticaria may be the cause. It is recommended that patients take medications such as desloratadine tablets or cetirizine hydrochloride tablets as prescribed.

5. Allergy

Allergy refers to an exaggerated immune response triggered by exposure to certain substances, which may lead to skin manifestations such as papules, erythema, and itching—potentially resulting in the aforementioned symptoms. Patients are advised to take medications such as loratadine hydrochloride tablets or levocetirizine hydrochloride dispersible tablets under medical supervision.

Patients are encouraged to seek timely medical attention when experiencing discomfort and to undergo standardized treatment under a doctor's guidance, which helps promote recovery.
