Red spots appear on the calves

The appearance of red spots on the feet and calves is likely to be allergic purpura. This disease is generally caused by pollen or drugs. The most obvious symptom is the appearance of large areas of red spots. Allergic purpura generally heals on its own, so you don’t have to worry too much. You must be careful not to come into contact with allergens. Although purpura is not a serious disease, it should not be underestimated. If it is serious, it is best to seek medical attention immediately.

For most patients with purpura, the recurrence of red spots on the skin is the biggest problem in their recovery. Only when the red spots on the skin gradually fade away and no new rashes appear, will the patients put down their anxious hearts. However, is purpura just those red spots on the skin?

In fact, this is not the case. Purpura is good at "disguise". The purpura on the surface is a rash, but in fact there are other manifestations. So how can patients identify their true face?

First, the skin symptoms. A rash is the first symptom of purpura. In the early stages of purpura, symmetrically distributed maculopapular purpura of varying sizes will appear near the joints of the lower limbs or on the buttocks, and it is easy to recur, often occurring on the limbs and buttocks.

Second, joint symptoms. If the patient develops joint swelling and pain 3-4 days after the onset of purpuric rash, single or multiple migratory joint pains may occur, and arthritis may also occur. Patients usually suffer from it in the knees, wrists and other parts of the body.

Third, gastrointestinal symptoms. Some patients will experience abdominal pain as an early symptom. At this time, most patients will experience paroxysmal pain in the abdomen, often accompanied by nausea and vomiting, and some patients will even have symptoms of bloody stools.

Fourth, kidney symptoms. After the onset of purpuric rash, kidney involvement usually occurs within 2-4 weeks, and the patient will have hematuria or proteinuria. The color of blood in urine is flesh-colored and can usually be seen with the naked eye.

The most important thing is to find symptomatic treatment. Treatment according to different symptoms is the key.

In addition, many purpura patients have a common misunderstanding, which is that they think the disease will heal if the red spots on the skin gradually fade away, and they do not have regular follow-up visits. However, when purpura causes nephritis, the disease is relatively hidden and often difficult for patients to detect. Therefore, after treatment, patients should cooperate with doctors to regularly monitor the development of the disease, and if they are taking medication, remember to follow the doctor's instructions.
