How long does it take cellulitis to resolve?

Thanks for asking!: It depends on the causative agent, the choice of antibiotics, the area involved and if surgery is needed. Over all, it generally will take days for the infection to come under control with the antibiotics and then days weeks for things to resolve. Then months for the entire inflame process to return to nl.

What's the cause ?: As injured skin heals, the body creates inflammation to do so which means fresh blood goes to the area and with it, many kinds of healing factors and cells. One type is called melanocytes which carry our skin pigment melanin. A healing occurs, these cells get deposited int he area and give it the brownish coloration you see. Over time, there will be some fading as the injury matures.
