ok i just checked my blood sugar and it was 91, now when my blood sugar is over 110 i'm alright not feeling cold shaking and i would also get racing heart beat but once its below 110 thats when all of those start to happen but most of all my heart starts hurting and feel it beating really fast, now when it comes to night right before i go to bed it just drops below 100. someone said to me that its normal for it to drop night cause ur about to sleep, but for me its doesn't do that it cause all of these sypotoms between feeling ice cold racing heart and shaking, so if anyone can relate to this please leave a comment down below and i'll get back to u later in the day or will probably be up for a few cause my heart?
