Cellulitis is potentially serious as it spreads quickly and can lead to more serious complications. If it is not treated, the infection can spread to the blood or lymph nodes and in rare cases the infection can spread to the fascia which is the deep layer of tissue causing a disease called Necrotizing Fasciitis (flesh eating bacteria) which is a medical emergency that can lead to death. Treatment of cellulitis include:
- Rest of the affected area.
- Antibiotics: either oral or intravenous depending on the severity of cellulitis, the presence of risk factors and presence of complications.
- Pain killers.
- Debridement of the dead tissue.
- Hyperbaric oxygen therapy may be used in some cases.
Prevention is done by taking a good care of cuts, wounds and burns, if you develop signs and symptoms of cellulitis, seek medical help quickly to avoid complications. (see burn wound care at home)
