I have had a fasting blood glucose level of 124,121,126,147,132 over the last five days (testing on a friends machine as I have been having symptoms of diabetes - dry mouth for 4 weeks, fatigue, muscle weekness, tired eyes, thirsty etc). I don't have an appointment with the doctor for another 4 days, my question is, are the levels seriously high - should I ask for an emergency appointment or will waiting be ok?
