Whether erythema nodosum is curable or not depends on the severity of the disease and the treatment plan chosen. If the disease is mild, with small scattered nodules on both lower legs, it can fade on its own without treatment and is self-limiting. If the erythema is more numerous and deeper, painful to touch, and feverish, medication is needed, including oral glycopyrrolate capsules. In severe cases, glucocorticoids such as prednisone acetate tablets and trenbolone tablets can be added, and topical dinaide cream and mometasone furoate cream can be used, and acupuncture can also be chosen for treatment.
