Redness and swelling around the scab of a wound after a dog bite

Redness and swelling around the scab of a dog bite wound may be related to wound infection, soft tissue injury, or allergic reaction. After identifying the cause, seek medical attention promptly and maintain proper hygiene at the wound site.

1. Wound Infection

After a dog bite, it is important to maintain cleanliness at the wound site. Inadequate care or failure to disinfect the wound in time may allow pathogenic bacteria to invade and multiply, increasing the risk of wound infection and causing symptoms such as redness, swelling, and pain. Maintain good wound hygiene by rinsing with running water and, if necessary, disinfect with iodophor.

2. Soft Tissue Injury

Bite injuries can damage the local skin and underlying soft tissues, leading to rupture of small blood vessels. Once blood leaks into the surrounding tissue spaces, it accumulates locally, resulting in swelling and pain. Applying cold compresses is recommended, which can help reduce swelling and discomfort.

3. Allergic Reaction

If the skin is allergic to components in dog saliva, a hypersensitivity reaction may occur, causing redness, pain, and itching around the scabbed wound. In such cases, consult a doctor for anti-allergy medications such as ebastine tablets, loratadine tablets, or cetirizine hydrochloride tablets, which can alleviate allergic symptoms and support healthy skin recovery.

In addition, conditions such as urticaria or other skin disorders may also contribute. It is essential to visit a hospital immediately to determine the exact cause and receive appropriate treatment as directed by a physician.
