Why are scabs appearing on my body?
Scabs are a common symptom of skin infections, immune system skin disorders, and injury.
Scabs result from the healing process, in which new skin grows over damaged skin.
They may occur in conditions affecting one area of skin alone, or along with more generalized conditions, such as shingles, chickenpox, or eczema..
How long can a scab last?
Small cuts and scrapes will form a scab and heal within a few days. The scab helps protect the wound from dirt and germs while new skin grows underneath. Once a scab has formed, you may not need to use a bandage anymore. Although a healing wound or scab will itch, it’s best not to scratch or pick at scabs.
