Ето какво намерих,но не е много успокоително
Дано да няма място за притеснение
This rash is called petechiae or purpura. It is caused by ruptured blood vessels under the skin. Petechiae appear as tiny, red, pinpoint, flat spots. They look as if someone used a fine-tip red ink pen to put little dots on the skin. Purpura is similar, but is larger and can be more purple or blue in color. The two most important signs that you can use to distinguish these spots from other rashes are:
They don't blanch when you press on them. Many other kinds of spots, when pressed, will turn white or skin colored for 1 or 2 seconds, and then turn red again. Petechiae and purpura will stay red or purple. They won't blanch at all when pressed.
They are completely flat. Because they occur under the skin, you won't be able to feel any bump.
There is one situation where petechiae are not urgent. If your child has a very bad cough or is vomiting, the pressure in the head can cause little blood vessels in the skin of the face and neck to rupture and form petechiae. THESE PETECHIAE ARE OK. THEY ARE NOTHING TO WORRY ABOUT.
PETECHIAE OR PURPURA FOUND ANYWHERE ELSE ON THE BODY BESIDES THE FACE AND NECK COULD BE A SIGN OF A BLEEDING PROBLEM OR A SERIOUS INFECTION. YOU SHOULD SEE YOUR DOCTOR IMMEDIATELY DURING THE DAY, OR BE EVALUATED IN AN ER DURING THE NIGHT FOR THIS TYPE OF RASH.
There are many conditions in which petechiae may be seen. These conditions range from very minor to very major. The common causes of petechiae include local injury and trauma, allergic reactions, autoimmune diseases, viral infections that impair blood coagulation (clotting), thrombocythemia (an abnormally high platelet level), certain medical treatments such as radiation and chemotherapy, idiopathic thrombocytopenic purpura (ITP), leukemia and other bone marrow malignancies that may lower the number of platelets, and sepsis (bloodstream infection). Petechiae are normally seen right after birth in the newborn and after violent vomiting or coughing. Drugs such as the anticoagulants warfarin (Coumadin) or heparin, aspirin, and cortisone can also cause petechiae
