What are the causes of skin redness?

Skin redness itself has multiple causes. The bulk of it tend to be either inflammatory or infective. So inflammatory causes include things like thrombophlebitis, which is inflammation of veins in the area. Allergic reactions that could be to clothing, to detergents, to drugs. Skin conditions can also be associated with inflammatory causes, so things like eczema, dermatitis, all of them can also cause skin redness. In terms of infective causes, you've We've got cellulitis, which is probably the commonest cause, and that's generally seen in patients who have insect bites, tick bites, or immunocompromised diabetics, but again that can happen to anyone, so the bulk of the causes are either infective or inflammatory.
