Cellulitis: How long does it take to heal on legs?

Why do we need new flu shots every year?
With influenza virus, a new vaccine must be developed each year to adapt to the virus's changing structure.
Why won't my hives go away?
Hives are red, itchy welts that crop up on the skin. Allergic reactions and stress, among other triggers, can cause episodes of hives, which typically last several days to a couple of weeks. Cases that last six weeks or longer may be autoimmune hives.
How high a fever is too high?
A fever is the immune system's response to an infection or invader. Most fevers drop after people take over-the-counter medications. People should call a doctor if their fever reaches 103° F and go to an emergency room if it reaches 105°.
