I noticed I have some petechiae after my shower. Anything to worry about?

Petechiae. A medicine, such as Aspirin or blood thinners (anticoagulants). Infection that causes the buildup of toxin in the blood or tissues (sepsis). A bleeding or clotting disorder, such as hemophilia, von willebrand's disease, thrombocytopenia, or another less common bleeding or clotting disorder. Other diseases that affect clotting.
