Nonspecific: Your symptoms are nondiagnostic but could be due to inadequate sleep, depression,chronic stress and anxiety,anemia,low blood pressure,underactive thyroid,etc. I recommend seeing your physician who will take a thorough history and perform a complete physical examinition and then order appropriate tests in order to make a diagnos is, prescribe treatment and suggest any needed referrals.
