What are small red painless dots under the surface of skin?

Petechiae are small, red, pinpoint hemorrhages that occur when blood vessels break and blood leaks into the surrounding tissue. They are often seen on the skin, but can also occur on the mucous membranes. Petechiae are usually not painful and do not cause any symptoms. However, they can be a sign of a more serious underlying medical condition, such as a bleeding disorder, an infection, or a drug reaction. If you notice any petechiae, it is important to see a doctor to rule out any underlying medical problems.

Petechiae are often caused by trauma, such as a bruise or a cut. In these cases, the petechiae will usually resolve on their own within a few days. However, petechiae can also be a sign of a more serious underlying medical condition, such as:

* A bleeding disorder, such as hemophilia or von Willebrand disease

* An infection, such as sepsis or meningitis

* A drug reaction

* A connective tissue disorder, such as lupus or scleroderma

* A cancer, such as leukemia or lymphoma

If you notice any petechiae, it is important to see a doctor to rule out any underlying medical problems. Your doctor may recommend blood tests, imaging studies, or other tests to determine the cause of the petechiae. Treatment will depend on the underlying cause.

In most cases, petechiae are a harmless condition that does not require treatment. However, it is important to see a doctor if you notice any petechiae, especially if they are accompanied by other symptoms, such as fever, headache, or rash.
