Hi, i am 33 years old and diabetic. for some time now my sugar levels have been well controlled since i test 3 times a day. however, sometime last year i noticed that sometimes i have a certain sensation that i cant really explain well but i feel like a shock is going through my body and i almost lose recognition of where my am for a moment and that passes in a matter of seconds after which i feel my heart beating fast and a pain in my forehead and eyes and a bit of weakness which all passes in seconds and i become supernormal like nothing happened. it happens mostly when i run on the threadmill or go up a stairs even though it also happens when i am asleep sometimes or just idling. i have checked blood sugar reading just after these episodes but its not hypo and also i had an ECG and doctor says nothing abnormal about heart function. i am confused. thryroid tests, white and red blood cell checks as well as kidney and liver function tests all done and all within range
