What is erythema nodosum


Any serious illness causes fear, helplessness and anxiety. We are carefully trying to understand the reasons for its occurrence, to recall the first symptoms, to choose the optimal treatment. Nodular erythema of the lower extremities also raises these questions.

There are 5 types of nodal erythema, each of them will have its own characteristics in the treatment.

In newborns, toxic erythema may occur, which is considered normal for medical reasons. Such a phenomenon, as a rule, passes on its own within 7 days from the moment the child is born.

Infectious diseases can cause infectious erythema in both young patients and adults. Erythema of the legs may appear due to a cold, exudative erythema, and will be accompanied by weakness, headache, discomfort in the joints and throat.

A tick bite sometimes causes Lyme disease, which causes migrating erythema. A ring-shaped form of the disease occurs due to allergies, poisoning and infection.

Why does this disease appear?

  • Tuberculosis;
  • Lupus;
  • Colitis caused by an ulcer;
  • Infection;
  • Arthritis;
  • Crohn's disease;
  • Tumors of different nature.

Sometimes it is impossible to identify the main disease, then the nodal erythema will be an independent disease.

Another of the reasons is the use of various medications:

  • Drugs, which include sulfur;
  • Estrogen containing drugs;
  • And others.

Since the disease affects the limbs, the health of the blood vessels will play a big role. And at risk are people suffering from varicose veins or inflammation of the venous walls with the formation of blood clots.

Symptoms of nodular erythema
