What Causes Swollen Lymph Nodes?

Cellulitis

Cellulitis occurs when bacteria infect the skin and the tissues directly below the skin. Many types of bacteria can cause cellulitis, though some being more common than others. Individuals are more likely to develop cellulitis if they have open wounds like scratches, surgical wounds, ulcers, sores, or punctures. The lymph nodes that become enlarged will vary depending on where the infection is. Other common symptoms include swelling, tenderness, pain, redness, and the affected area being warm to the touch. The infection often occurs in the legs, but it can develop anywhere in the body. This is not a contagious infection. If cellulitis spreads to other organs of the body, it can cause life-threatening complications. Cellulitis that has spread becomes an emergency medical condition that requires immediate treatment. The main treatment for cellulitis is a course of oral antibiotics, or intravenous antibiotics in severe cases.
