Inflammation of the cellular tissue, also known as cellulitis, there are no topical medications for fast recovery for this disease, and treatment includes local incision and drainage, combined with systemic application of sensitive antibiotics. Cellulitis is a purulent disease caused by infection of subcutaneous, subfascial, intermuscular spaces or deep connective tissues, and is most often caused by β-hemolytic streptococcal infections, with group A streptococcus and Streptococcus pyogenes being the most common. Due to the depth of the infection, topical medications cannot penetrate deep enough to treat the infection. When cellulitis shows signs of abscess formation such as fluctuating sensation, local incision and drainage is feasible, along with a combination of oral or intravenous sensitive antibiotics. Cellulitis lesions without ulceration can be used externally with magnesium sulfate solution and other wet compresses, to relieve the local redness, swelling, pain and other symptoms, but the drug has no anti-infective effect, no therapeutic effect. It is recommended that patients suffering from cellulitis go to regular hospitals in a timely manner, under the guidance of the doctor to standardize the application of medication, to avoid the delay of self-medication, resulting in serious adverse reactions.
