What can I do for my cellulitis without going to a doctor?

Cellulitis? Cellulitis-infection of the skin of a bacterial origin. It is usually warm tender, red, expanding region of the body surface; it can be accompanied by a fever, pain. You must see a medical professional, if new&very mild an immediate appt. If unsure-go to the er. This is especially true if you are immune deficient-diabetic, poor circulation, elderly. Blood clots could also be a dx-med emergency.
Not a good idea. If what you have is truly cellulitis (a bacterial infection of the skin), it is likely to continue to get worse until you treat it with appropriate antibiotics.
