Introduction
Itching around the scabbed wound and the presence of small blisters may be normal, but could also be caused by allergic dermatitis, local infection, or other conditions. In such cases, appropriate treatment should be based on the underlying cause. Besides these common reasons, other factors such as eczema, phlebitis, or fungal infection might also be responsible. Patients should pay attention to proper wound care and avoid excessive scratching.
Itching around the scab of a wound, along with small blisters, may be a normal phenomenon, but could also result from allergic dermatitis, local infection, or other causes. In such cases, appropriate management should be based on the underlying cause. The details are as follows:
1. Normal Phenomenon
Blisters around a healing wound may arise from localized soft tissue proliferation and are often accompanied by mild itching. This is a normal part of the wound healing process and generally does not require concern.
2. Disease-Related Causes
2.1 Allergic Dermatitis
If a patient has sensitive skin or is allergic to certain medications, a local allergic reaction may occur, leading to symptoms such as blisters, redness, swelling, and itching. It is usually recommended to use calamine lotion topically or take antihistamines such as loratadine tablets under medical guidance.
2.2 Local Infection
Poor wound care can allow bacteria to grow at the site, resulting in wound infection. Symptoms include local rashes, pus discharge, and exudation. In such cases, topical antibiotics such as erythromycin ointment or mupirocin ointment should be used as directed by a physician to alleviate symptoms.
In addition to the above common causes, other factors such as eczema, phlebitis, or fungal infections may also be responsible. Patients should maintain proper care of the affected area and avoid excessive scratching to prevent secondary infection.
