Cellulitis symptoms can occur at the location of the infected skin (local symptoms) or they can occur on other parts of the body (systemic symptoms). Symptoms of cellulitis that occur at the location of the infected skin have four common characteristics: redness, warmth, swelling, and pain when touched. Cellulitis symptoms that affect the whole body may cause a person to experience flu-like symptoms (such as fever, chills, and muscle aches). People with cellulitis can also rarely develop complications, including toxic shock-like syndrome, spreading of the cellulitis to the heart (endocarditis) or bone (osteomyelitis), an abscess (a pus-filled cavity resulting from inflammation), or even loss of life.
