Doctor: Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.  Petechiae means platelet dysfunction. Therefore, check your platelet count immediately.  Also check for prothrombin time and INR etc.  Until examination is done it is difficult to say what it is.  Please consult your physician immediately he will examine and treat you accordingly.  Take care.
