dear doctor my father suddenly woke up and said he felt dizzy and had numbness in his left palm. he himself being a doctor, he felt it was due to high blood pressure. we went to the hospital and they found he had a very low blood sugar and high blood pressure. they treated him for it. as he had a mild heart attack before they preformed an ECG and found minor changes and after about six hours they performed some blood test which they said would be effective only after six hours and found nothing wrong. he has little nystagmus. they sent him home and asked us to consult a neurologist and get a CT scan of the brain done some time this week. this happened on sunday. on monday and tuesday he was perfectly fine. today they went to a neurologist and he said CT would not be required and sent him to the ophthalmologist. my query is doctor could this be an anxiety disorder because he is not a diabetic or a hypoglycemiac neither a hypertension patient. moreover i have some doubts regarding that blood test they did. i mean they said it would be effective only after six hours and i am doubtful whether they might have taken the test before six hours.
