How often do I have to check on my sugar level? My mother is diabetic and I had my test last week however, it was normal. How often do I have to check on my sugar level?

As you said, your mother is diabetic, if you are diabetic though your sugar level are within normal limits, you have to have check up monthly, if not diabetic every six months is advised.

Is checking one's sugar level painful? How do you go about doing that? Do you have to draw blood to find out?

These days the blood drawing is pretty painless. It just feels like
a pinprick and you need very little blood for the latest machines.
