Fever,shaking,fatigue,dizziness,lightheadedness,muscle aches,warm skin,sweating
Cellulitis of floor of mouth can lead to Ludwigs angia
Cellulitis of lower limb Are Infection of skin & subcutaneous tissue showing distinct margins with Fever & malaise

ETIOLOGY & RISK FACTORS:

Cellulitis occurs when certain types of bacteria enter through a cut or crack in the skin.
Cellulitis is commonly caused by Staphylococcus aureus and Streptococcus bacteria Clostridium perfringens.
