Symptoms of erythema nodosum

Many people don’t understand erythema nodosum. Generally, patients with erythema nodosum just feel a little uncomfortable and a little itchy and painful at the beginning. Many people think it is a mosquito bite and don’t pay much attention to it, so they miss the best time for treatment. So how to treat it? The details are as follows:

This disease is a skin allergy caused by many reasons, and the true pathogenesis is still unclear. Some people believe that the disease is a delayed hypersensitivity reaction of blood vessels to microorganisms or other antigens. Different treatments can be used according to different situations.

1. Systemic treatment

(1) Find the cause and provide appropriate treatment. During the acute phase, you can rest in bed, elevate the affected limb, and avoid cold and strenuous labor. For those with obvious infection foci, antibiotics can be used in combination.

(2) For patients with more severe pain, oral analgesics and non-steroidal anti-inflammatory drugs, such as indomethacin (Indomethacin) and ibuprofen, can be taken. For those with obvious infection, give antibiotics. In severe cases, corticosteroids, such as prednisone (Kedison) or betamethasone/betamethasone dipropionate (Diprosone), can be given by intramuscular injection once every 3 weeks to quickly control the disease. In addition, 10% potassium iodide mixture can be used, 3 times a day, for 2 to 4 weeks. This method is safe and effective, but it should be noted that long-term use may lead to hypothyroidism. For patients with stubborn illness, hydroxychloroquine and dapsone can be used, or the Chinese medicine Tripterygium wilfordii tablets or Kunming Shanhaisu tablets can be taken. Systemic treatment can also be done with ultraviolet light, wax therapy, diathermy or audio-frequency electrotherapy.

2. Local treatment

The principles of local treatment are anti-inflammatory and analgesic. For external use, fish boron ointment, 10% camphor ointment or 75% alcohol local wet compress can be used. In addition, corticosteroid ointment can be applied externally to relieve pain. You can also inject about 0.3 ml of triamcinolone suspension added to 2% procaine solution into the skin lesions, which has a significant effect on those with persistent and severe pain in the nodules.

I would like to give you a sincere suggestion that if you have this disease, you must seek timely treatment, because this disease is particularly easy to prolong, and may cause recurrence of other diseases or cause other diseases such as leukemia, which is common in our lives. If you have this disease, you must maintain good personal hygiene and remember not to come into contact with raw water.
