Erysipelas is an acute inflammation of the skin and reticular lymphatic vessels. The onset of erysipelas is due to hemolytic streptococci invading the skin and mucosal reticular lymphatic vessels through small wounds in the skin mucosa. Erysipelas commonly occurs on the lower limbs and face, progressing rather quickly, with seldom tissue necrosis, and a tendency for recurrent episodes. The local symptoms include patchy erythema, bright red color, lighter in the center, with clear and slightly raised edges.

How is erysipelas treated?

Erysipelas is mainly caused by a bacterial infection of the lymphatic system, resulting in lymphangitis, primarily affecting the superficial lymphatics of the skin's dermis. The common pathogen is Group A hemolytic streptococcus. For erysipelas, proactive anti-infection treatment is necessary, typically opting for penicillin-class antibiotics. For patients allergic to penicillin, other types of antibiotics such as cephalosporins or macrolide antibiotics can be considered. If there is significant local swelling and pain, magnesium sulfate can be used for local wet compresses to reduce swelling and alleviate pain. Additionally, traditional Chinese medicine treatments can be considered, such as taking oral medications that clear heat and detoxify.

What foods are good to eat for erysipelas?

Erysipelas is usually caused by a bacterial infection in the lymphatic vessels. Infant patients should maintain a light and nutritious diet, avoiding irritant foods. Details are as follows: First, one can eat light and easily digestible foods, such as celery, which have the effect of clearing heat and detoxifying. Patients can use these in moderation. Second, avoid spicy and greasy foods, strong tea, and coffee, all of which can be irritating. When the body is weak, it is advisable to avoid these. Similarly, lamb and leeks, which have a warming and tonifying effect, should also be used cautiously to prevent exacerbating the symptoms of erysipelas due to excessive internal heat. Third, consuming foods rich in proteins, vitamins, and minerals, such as fresh vegetables, lean meats, and eggs, can enhance the body's resistance and have an anti-disease effect.

What is erysipelas and is it contagious?

Erysipelas is an inflammation of the skin and lymphatic vessels caused by bacterial infection, commonly occurring in the summer and autumn seasons. It frequently occurs on the face and lower legs, with rhinitis and athlete's foot being the most common triggers. This is due to bacteria infecting the lymphatic vessels through minor wounds. Initially, the lesions are clearly defined, edematous, bright red patches with distinct edges, shiny surface, and increased skin temperature in the affected area. Occasionally, blisters or large blisters may appear, accompanied by spontaneous pain or tenderness and local lymph node enlargement. Erysipelas is not contagious and is quite sensitive to antibiotic treatment. The preferred treatment is penicillin for a duration of two weeks. Since erysipelas is prone to recurrence, it is crucial that the treatment course is sufficient.

What is the best medicine for erysipelas?

Erysipelas is an infectious disease that commonly affects the lower legs and face. Once erysipelas is diagnosed, penicillin is the recommended treatment. However, if there is an allergy to penicillin, cephalosporins or quinolones can be used as alternatives. Generally, intravenous infusion is necessary; oral administration alone is not effective. Intravenous medication is required to achieve the best anti-inflammatory treatment results.

How many days does it take for penicillin to take effect on erysipelas?

Erysipelas is treated with penicillin, generally requiring about ten days to take effect, and medication should not be discontinued even after ten days. This is because this period is just when the drug starts to work and relieve the disease; it still requires about another seven days of usage to completely fight the bacteria and avoid the possibility of recurrence. Erysipelas has a high recurrence rate, so it is crucial to ensure thorough treatment.
