Reddish bruise-like spots appearing after scratching the body may be caused by excessive scratching, contact dermatitis, skin allergy, or other reasons, and different conditions require different treatments.

1. Excessive Scratching

If the external weather is dry, reduced moisture in the skin and mucous membranes can lead to itching. Vigorous scratching may cause local blood vessels to rupture. Applying a warm towel or hot water bottle to the affected area can help, as heat promotes local blood circulation and accelerates recovery.

2. Contact Dermatitis

Contact dermatitis is a common skin condition. When the skin is irritated by external substances, itching occurs and the permeability of local blood vessels increases. Scratching with hands may result in red marks. Under a doctor's guidance, topical medications such as calamine lotion, mupirocin ointment, or erythromycin ointment can be applied for treatment.

3. Skin Allergy

Skin allergic reactions can cause redness and swelling, and may also lead to rupture of subcutaneous capillaries, resulting in congestion. Patients can take antihistamines such as loratadine tablets, levocetirizine hydrochloride tablets, or epiastine hydrochloride tablets under medical supervision.

In addition, reddish bruise-like spots after scratching could also be due to Henoch-Schönlein purpura (allergic purpura). In such cases, medications like cetirizine hydrochloride syrup or chlorpheniramine maleate tablets may be taken under a doctor’s guidance. Patients should seek timely medical attention to identify the underlying cause and receive appropriate targeted treatment. Proper local care during treatment is essential to restore normal health.
