Purple streaks on the inner side of the arm
Purple streaks on the inner side of the arm may be caused by rapid fat accumulation, allergies, trauma, varicose veins, or telangiectasia. Appropriate treatment should be selected under medical guidance. Specific analysis is as follows:
1. Rapid Fat Accumulation
Overeating and irregular eating habits can cause muscles or fat in the arm to increase in volume too quickly, exceeding the skin's ability to stretch. This may lead to rupture of elastic fibers in the dermis, resulting in purple streaks. This is a normal condition that does not require special treatment. Maintaining a healthy weight through portion control, eating smaller meals more frequently, avoiding overeating, and engaging in regular physical exercise is recommended.
2. Allergy
Certain medications, cosmetics, or skincare products may trigger allergic reactions. Such reactions can cause redness, swelling, and the appearance of purple streaks on the skin. Under medical supervision, antihistamines such as cetirizine hydrochloride tablets or loratadine tablets may be used to relieve symptoms.
3. Trauma
If the inner arm suffers injury—such as pressure or impact—local capillaries may rupture, leading to subcutaneous bleeding. Over time, this may appear as purple bruising. These patients typically have a history of injury and may experience tenderness at the site. It is recommended to follow medical advice and apply local heat therapy or massage to improve blood circulation and accelerate the absorption of bruising.
4. Varicose Veins
Varicose veins occur when venous blood flow is obstructed, causing vein dilation and blood accumulation. This could be one of the reasons for purple streaks appearing on the inner arm. Wearing compression stockings may help improve the condition.
5. Telangiectasia
Telangiectasia is a relatively common benign skin condition. The exact cause is unknown but may be related to genetic factors, abnormal estrogen levels, or infections. It may present as red patches on the skin surface. Local treatments such as electrocautery or electrodessication may be considered to improve appearance.
It is advisable to seek timely medical evaluation to determine the underlying cause with the help of a healthcare professional and receive targeted treatment. Avoid self-medicating to prevent adverse reactions.
