What is the reason why small red spots appear on the child’s face after vomiting?

If we are not feeling unwell, we may not vomit at all. Of course, there are many reasons for vomiting, such as motion sickness or drunkenness, but few people vomit for no reason, so frequent vomiting is basically a disease. So, after vomiting, many red spots appear on the face. What disease is this? Some experts point out that this symptom is caused by a disease called allergic purpura.

Symptoms of Henoch-Schonlein Purpura

How to determine whether a child has Henoch-Schönlein purpura? Parents need to recognize the following symptoms:

1. Respiratory tract infection. Children often have a history of upper respiratory tract infection 1-3 weeks before onset of illness.

2. Skin symptoms. Petechiae appear on the skin. These petechiae mostly appear around the joints of the child's lower limbs and buttocks. The purpura is symmetrically distributed, appears in batches, varies in size, and varies in color. It can merge into patches and usually gradually disappears within a few days, but may recur. Symmetrical maculopapular purpura of varying sizes appears in batches near the large joints of the limbs and buttocks, recurring on the limbs and buttocks, and rarely involving the face and trunk. The skin lesions initially present with itching, small urticaria, angioedema and erythema multiforme.

3. Joint symptoms. Children may have single or multiple, migratory joint swelling and pain or arthritis, sometimes with local tenderness, which often occurs in joints such as the knees, ankles, elbows, and wrists, and there may be exudate in the joint cavity.

4. There are gastrointestinal symptoms. For example, children may have paroxysmal abdominal colic or persistent dull pain, which may be mainly accompanied by vomiting, hematemesis or bloody stools. In severe cases, the stools may be bloody.

5. Kidney symptoms: Macroscopic hematuria or microscopic hematuria, proteinuria and tubular urine usually appear about 2-4 weeks after the onset of purpura. They may also appear after the rash subsides or when the disease is dormant.
