What is a peticial rash?

A petechial rash is a type of skin rash that is characterized by small, round, red or purple spots that do not blanch when pressure is applied. Petechiae are caused by bleeding from small blood vessels in the skin, and they can be a sign of a variety of underlying medical conditions.

Some of the most common causes of petechiae include:

* Trauma: Petechiae can be caused by any type of trauma that damages the skin, such as a bruise or a cut.

* Infections: Petechiae can be a symptom of a variety of infections, including bacterial infections, viral infections, and fungal infections.

* Medications: Some medications, such as aspirin and blood thinners, can cause petechiae.

* Blood disorders: Petechiae can be a sign of a blood disorder, such as thrombocytopenia (low platelet count) or leukemia.

* Other medical conditions: Petechiae can also be a symptom of other medical conditions, such as vasculitis (inflammation of the blood vessels), Cushing's syndrome, and scurvy.

In most cases, petechiae are not a serious medical condition and they will go away on their own within a few days. However, if you are experiencing petechiae along with other symptoms, such as fever, headache, or confusion, it is important to see a doctor right away.
