I am so stupid, should I go to my doctor for ablood test. also I have this constant twitch in my right eye. Christina.
Twitching in the right eye is very common and usually nerve irritation which is worsened by stress such as sleep deprivation from staying out late and Chat Doctor.  There are no blood tests which will explain your symptoms unless you are having bleeding from somewhere that would cause anemia or a worsening of a problem you already have.  It is most likely blood pressure fluctuations.  Wait until you have fully recovered from your night out and then reassess the symptoms.  When you get try symptoms if sitting down/laying down or doing toe raises improves the symptoms then it is a blood pressure problem.  If not the next most common reason is an ear problem
